Question: How many impromptu locations did Paul McCartney go to promote his fourteenth solo album?

full_context: Document 1: Off the Ground: Off the Ground is the ninth solo studio album by Paul McCartney under his own name (discounting then his Wings-era discography, among other releases), released in 1993. As his first studio album of the 1990s, it is also the follow-up to the well-received "Flowers in the Dirt" (1989).
Document 2: Unplugged (The Official Bootleg): Unplugged (The Official Bootleg) is a live unplugged performance by Paul McCartney, recorded and released in 1991. Following the vastness of his world tour recently captured on "Tripping the Live Fantastic", McCartney relished the opportunity to strip back his songs and appear on the newly launched acoustic-only show "MTV Unplugged". Consequently, McCartney was the first in a long line of artists to release an unplugged album.
Document 3: Memory Almost Full: Memory Almost Full is the fourteenth solo studio album by Paul McCartney, discounting his Wings-and-Beatles-era discography, his orchestral works and his output as the Fireman. It was released in the United Kingdom on 4 June 2007 and in the United States a day later. The album was the first release on Starbucks' Hear Music label. It was produced by David Kahne and recorded at Abbey Road Studios, Henson Recording Studios, AIR Studios, Hog Hill Mill Studios and RAK Studios between October 2003, and from 2006 to February 2007. In between the 2003 and 2006 sessions, McCartney was working on another studio album, "Chaos and Creation in the Backyard" (2005), with producer Nigel Godrich.
Document 4: McCartney (album): McCartney is the debut studio album by English musician Paul McCartney. It was issued on Apple Records in April 1970 after McCartney had resisted attempts by his fellow Beatles to have the release delayed to allow for Apple's previously scheduled titles, notably the band's "Let It Be" album. McCartney recorded this solo album during a period of depression and confusion, following John Lennon's private announcement on September 20, 1969 that he was leaving the Beatles, and the conflict over its release further estranged McCartney from his bandmates. A press release in the form of a self-interview, supplied with UK promotional copies of "McCartney", led to the announcement of the group's break-up on 10 April 1970.
Document 5: Me (James McCartney album): Me is the first full length studio album by James McCartney, son of Paul and Linda McCartney. It was recorded between Abbey Road, Hog Mill, Select, Avatar and Nevo studios and was produced and mixed by David Kahne. It also includes performances from Paul McCartney. James McCartney said of the album "it's about having as much emotion as possible for me, musically and lyrically. Cathartic, heartfelt and true."
Document 6: Driving World Tour: The Driving World Tour was Paul McCartney's first concert tour of the 21st century and of any kind since 1993's New World Tour. For the first time in nearly a decade, McCartney returned to the road following the death of first wife, Linda McCartney, the death of George Harrison, and 9/11. This was in promotion of his 2001 album "Driving Rain". Paul "Wix" Wickens returned on keyboards and is credited as Musical Director. New to the fold were Americans Rusty Anderson, Brian Ray, and Abe Laboriel Jr. Paul McCartney's then-fiancée Heather Mills accompanied him on the tour and was in the audience for every American performance.
Document 7: Return to Pepperland: Return to Pepperland is a cancelled Paul McCartney album recorded in 1984–1987. The album was built up of mostly home demos and was a reflection of work from McCartney's career as a member of the English rock band the Beatles. Although it was made around twenty years after the release of the Beatles' 1967 album "Sgt. Pepper's Lonely Hearts Club Band" (which inspired it), some tracks which made their way onto the bootleg were written whilst McCartney was in the Beatles, including the Lennon–McCartney-written "Love Me Do" and "P.S. I Love You". Other songs turned up on CD-single B-sides including the McCartney/Stewart song "Don't Break the Promise".
Document 8: Kisses on the Bottom: Kisses on the Bottom is the fifteenth post-Beatles studio album by Paul McCartney (discounting his Wings-era discography, his orchestral works and his output as the Fireman), consisting primarily of covers of traditional pop music and jazz. Released in February 2012 on Starbucks' Hear Music label, it was McCartney's first studio album since "Memory Almost Full" in 2007. The album was produced by Tommy LiPuma and includes just two original compositions by McCartney: "My Valentine" and "Only Our Hearts". The former features Eric Clapton on guitar, while the latter features Stevie Wonder on harmonica. "Kisses on the Bottom" peaked at number 3 on the UK Albums Chart and number 5 on the US "Billboard" 200, while also topping "Billboard" magazine's Jazz Albums chart.
Document 9: Press to Play: Press to Play is the sixth post-Beatles studio album by the English musician Paul McCartney (outside of Wings' body of work), released in August 1986. It was McCartney's first album of entirely new music since "Pipes of Peace" in 1983, and his first solo album to be issued internationally by EMI following a six-year alliance with Columbia Records in the United States and Canada. Keen to re-establish himself after his poorly received 1984 musical film "Give My Regards to Broad Street", McCartney enlisted producer Hugh Padgham to give the album a contemporary sound.
Document 10: Paul McCartney's Secret Tour 2007: The Secret Tour 2007 was a European & US impromptu tour of six "secret" shows in small venues by Paul McCartney scheduled to promote the release (just before the tour on 4 June 2007) of the "Memory Almost Full" studio album.
Document 11: Seven Tour: Seven Tour is a concert tour by British singer Lisa Stansfield, in support of her 2014 album "Seven". During the tour Stansfield performed her hit songs along the new tracks from her latest album, including "Can't Dance," "Stupid Heart," "Conversation" and others. The tour started on 16 May 2013 in Paris, France and ended on 4 November 2014 in Riga, Latvia. Stansfield played over 60 concerts in Europe. The show at the Bridgewater Hall in Manchester on 7 September 2014 was recorded for a forthcoming live DVD due for release on 25 August 2015. It is titled "Live in Manchester".
Document 12: Chaos and Creation in the Backyard: Chaos and Creation in the Backyard is the thirteenth solo studio album by Paul McCartney, released in 2005. A long time in the making, the set was produced by Radiohead and Beck collaborator Nigel Godrich at George Martin's suggestion.
Document 13: Paul McCartney: Many Years from Now: Paul McCartney: Many Years from Now is a 1997 biography of Paul McCartney by Barry Miles. It is the "official" biography of McCartney and was written "based on hundreds of hours of exclusive interviews undertaken over a period of five years", according to the back cover of the 1998 paperback edition. The title is a phrase from McCartney's song "When I'm Sixty-Four", from the Beatles' 1967 album "Sgt. Pepper's Lonely Hearts Club Band". The book was first published in the United Kingdom in October 1997 by Secker & Warburg.
Document 14: Flaming Pie: Flaming Pie is the tenth solo studio album by Paul McCartney under his own name, first released in 1997. His first studio album in over four years, it was mostly recorded following McCartney's involvement in the highly successful "Beatles Anthology" project. The album was recorded in several locations over two years, 1995 and 1997, featuring two songs dating from 1992. The album featured several of McCartney's family members and friends, most notably McCartney's son, James McCartney. In "Flaming Pie"'s liner notes, McCartney said: ""[The Beatles Anthology]" reminded me of The Beatles' standards and the standards that we reached with the songs. So in a way it was a refresher course that set the framework for this album."
Document 15: Temporary Secretary: "Temporary Secretary" is a song by Paul McCartney, featured on his 1980 album "McCartney II". In 2013, "Rolling Stone" ranked it the #36 all-time McCartney post-Beatles song, calling it a "cult favorite" and an "oddly catchy electro-pop nugget, about a slightly creepy-sounding guy looking to hire a temp." In 2014, "Temporary Secretary" was ranked the 167th greatest song of all time by critics of "NME" magazine. They described it as "wonky electropop that didn't sound so much ahead of its time as out of it altogether."
