"Memory of a Free Festival" is a 1970 single by David Bowie. The song had originally been recorded in September 1969 as a seven-minute opus for Bowie's second self-titled album (reissued as Space Oddity in 1972). It was reworked in March-April 1970 at the behest of Mercury Records, the label believing that the track had a better chance of success as a single than "The Prettiest Star", released earlier in the year.
