"You and Me (Babe)" is a song by English musician Ringo Starr, released as the final track on his 1973 album "Ringo".
 Starr's fellow ex-Beatle George Harrison wrote the song along with Mal Evans, the Beatles' longtime aide and a personal assistant to Starr during the making of "Ringo".
 The track serves as a farewell from Starr to his audience in the manner of a show-closing finale, by lyrically referring to the completion of the album.
 During the extended fadeout, Starr delivers a spoken message in which he thanks the musicians and studio personnel who helped with the recording of "Ringo" – among them, Harrison, John Lennon and Paul McCartney, and his producer, Richard Perry.
Lancashire Hustler is an album by Keef Hartley.
 This album is credited as a solo effort by Hartley, with Robert Palmer, Elkie Brooks and Pete Gage of the band Vinegar Joe (with whom Hartley worked on the 1972 album "Rock and Rock Gypsies") providing support on some tracks.
Live at the Greek Theatre 2008 is a live album released by musician Ringo Starr & His All-Starr Band in 2010.
 It is one of few current albums that Ringo Starr has released on a major label, this one being released on Universal Music Group, as well as his 2008 studio album "Liverpool 8", which was released under Capitol Records.
 One of the reasons that this particular live album might have been released on a more popular label is because the Greek Theatre (located in Los Angeles) is more of a bigger venue then some of Ringo's other concert locations.
 The album oddly removes many of the songs that were sung at the concert.
 On the filmed concert, also included with the CD, there are several more songs.
 Such examples are Edgar Winter's "Frankenstein" and what would have been an obvious choice for the album, a live version of Ringo Starr's "Liverpool 8" song.
 Also, there is a sing-along version of John Lennon's "Give Peace a Chance".
 News of the album was originally revealed on the Beatles' official website as well as Ringo's official website.
The Battle of North West Six is the second album by the Keef Hartley Band.
 At the time, Hartley's six-piece group was appearing augmented with a brass section as The Keef Hartley Big Band, and a number of songs on the album feature this extended line-up.

 Born Alan Ernest Caldwell in Liverpool, Storm was the singer and leader of Rory Storm and the Hurricanes, a Liverpudlian band who were contemporaries of the Beatles in the late 1950s and early 1960s.
 Ringo Starr was the drummer for the Hurricanes before joining the Beatles in August 1962, replacing original drummer Pete Best.
Lyn Dobson is a British musician, noted as a jazz-rock flautist and saxophonist.
 He appeared with Georgie Fame and the Blue Flames and Manfred Mann in the mid-1960s, and then with Soft Machine and Keef Hartley, as well as playing on albums by Nick Drake and John Martyn.
 Dobson played the flute solo on Manfred Mann's "Pretty Flamingo".
