To celebrate what would have been his 74th birthday this Friday, David Bowie's previously unreleased cover versions of John Lennon’s Mother and Bob Dylan’s Tryin’ To Get To Heaven will be released as a limited edition 7" single.

Originally recorded by Lennon for his 1970 album John Lennon/Plastic Ono Band, Bowie's version of Mother was produced by Tony Visconti in 1998 for a Lennon tribute that never came to fruition.

Dylan’s original Tryin’ To Get To Heaven appeared on his 1997 Time Out Of Mind, with Bowie’s version recorded in February 1998 during the mixing sessions for the live album LiveAndWell.com.

The new 7" single is limited to 8147 numbered copies, 1000 of which will be on cream-coloured vinyl available only from the official David Bowie store and Warner Music’s Dig! store (the remainder will be black). Both tracks will be available to stream and download.
