Paul McCartney has spoken out about the forthcoming remastered re-release of his and Linda McCartney‘s 1971 album RAM, saying it reminds him of his “hippie days”.

The album, which was McCartney’s second LP after the demise of the Beatles and the only album to be credited to him and his former wife, Linda, will be re-released in the UK on May 21. A deluxe edition box set will include a 112-page book, photo prints, copies of handwritten lyrics and notes and four CDs as well as a film that tells the making of the album on DVD, Ramming.

Written by the McCartneys on their farm in Mull of Kintyre, Scotland, the album was recorded in New York with Denny Seiwell, David Spinozza and Hugh McCracken. Of the re-issue, McCartney has said:

“Ladies and gentlemen, this is an album from a long, long time ago, when the world was different. This is an album that is part of my history – it goes back to the wee hills of Scotland where it was formed. It’s an album called ‘RAM’. It reminds me of my hippie days and the free attitude with which was created. I hope you’re going to like it, because I do!”

‘RAM’ will be available in standard, special and deluxe editions, as well as on vinyl, limited edition mono vinyl and digital.
