 After release of this album, Kaukonen and Jack Casady began to perform as "Jack & Jorma, The Original Acoustic Hot Tuna" and Falzarano and Sears performed much less with Hot Tuna and Kaukonen's solo act, with Sears finally leaving in 2001 and Falzarano leaving in 2002.

 In April 1989, the tour was nominated for "Tour of the Year 1988" at the inaugural International Rock Awards.
The Greatest Hits Tour was the seventh concert tour by Australian singer Olivia Newton-John, in support of her seventeenth studio album "Back with a Heart" (1998).

Tattoos & Tequila is the third solo studio album by Mötley Crüe frontman Vince Neil.
 It is his first solo release in 7 years since the live album "" in 2003 and first solo studio album in 15 years since 1995's "Carved in Stone".

American singer Beyoncé has embarked on six concert tours during her solo career, four of which have been worldwide and two of which have been collaborative.
 Her solo tour debut (whilst on hiatus with Destiny's Child) began in 2003, with the Dangerously in Love Tour.
 Based predominantly in the United Kingdom, the tour received an unfavorable review from Dave Simpson of "The Guardian" based on Beyoncé's costumes and a confusion of her core audience at the time.
 In 2007, she embarked on her first major solo world tour – The Beyoncé Experience, following Destiny's Child's disbandment in 2005.
 The tour visited five continents and Beyoncé was lauded by music journalism for her simultaneous dancing and singing abilities.
 Following the release of her 2008 third studio album "I Am... Sasha Fierce", Beyoncé embarked on her next world concert venture, the I Am... World Tour.
 She collaborated with Thierry Mugler exclusively for the tour's costumes.
 The I Am... World Tour also marked the first time Beyoncé had performed in South American countries.
 Beyoncé saw her most commercially successful tour to date with 2013-2014's The Mrs. Carter Show World Tour.
 Grossing US $229,727,960, the 132 date venture was criticised for the name of the tour, as Beyoncé appeared to be letting herself be known as simply Shawn "Jay-Z" Carter's wife, despite being proclaimed as a "modern-day feminist".
 The tour itself however was lauded by music critics, who again praised Beyoncé's performance abilities and the more advanced production seen compared to her previous tours.
Ms. Kelly is the second solo studio album by American recording artist Kelly Rowland.
 It was released on June 20, 2007 through Columbia Records in collaboration with Music World Entertainment.
 Originally titled "My Story" and expected for a mid-2006 release, the album marked Rowland's first solo studio album in four years.
 Retitled and delayed numerous times prior to its official release, the album's release date was eventually moved to 2007 in favor of a multi-tiered marketing strategy and additional recording sessions.
 Willed to produce a more personal effort after her debut studio album "Simply Deep" (2002), Rowland contributed nine tracks to the reworked "Ms. Kelly", which took her solo work further into urban music markets, involving production by Scott Storch, Polow da Don, Soulshock & Karlin and singer Tank, among others.
Bad is the seventh studio album by American singer and songwriter Michael Jackson, released on August 31, 1987 in the United States by Epic Records and internationally by CBS Records.

 "Bad" was recorded during the first half of 1987.
 The lyrical themes include media bias, paranoia, racial profiling, romance, self-improvement and world peace.
 The album cemented Jackson's status as one of the most successful artists of the 1980s.
The Rattle That Lock Tour was a concert tour by English singer and musician David Gilmour to support his fourth solo studio album, "Rattle That Lock".
 The tour became a commercial success, grossing $47 million and selling 288,997 tickets in 16 shows in the 2015 total.
 It was the 76th highest grossing of the year, according to "Pollstar's" annual year end tour chart.

 The tour is documented on the live release "Live at Pompeii" (2017).
Seth Bogart is the second overall solo studio album written, recorded and performed by Hunx and His Punx vocalist Seth Bogart.
 It is the first studio album to be released under his name, as his previous solo record "Hairdresser" was issued under his stage name Hunx.
 Bogart had enjoyed making music as his Hunx character, but had wanted for a long time to start recording material that showed more of his true self, "like a weird teenager’s version of an adult album" as he said in an interview.
 Therefore, he decide to take more than two years to make the album, unlike during his Hunx period where he would make a record in five days or less.
 "Seth Bogart" was produced and co-written by Cole MGN, and also features vocal performances from Chela, Kathleen Hanna, Tavi Gevinson, Jeremiah Nadya and Clementine Creevy.
