- Tyrannosaurus Rex had headlined at the very first Glastonbury in September 1970, as last-minute replacements when The Kinks pulled out.
- Released in April 1972, the triple "Glastonbury Fayre" album featured contributions from a host of contemporary stars, including the Grateful Dead, David Bowie, Hawkwind, Brinsley Schwarz, the Pink Fairies, Pete Townshend and Marc Bolan.
- Bolan's contribution was a stereo home demo recording of a new song, "Sunken Rags", a veiled dig at the music industry of the time. This is now re-issued for the first time since 1972, on 7" orange vinyl.
- The B-side features the T. Rex studio recording of the song, along with "Jitterbug Love", both tracks appearing on the b-side of "Children Of The Revolution".
