A-side and B-side
On 2 July 2009, Aztec Music reissued "Universal Radio" with extensive liner notes, rare photos, and three bonus tracks. The first bonus track is a live recording from 1974 of their cover version of Fleetwood Mac's "Black Magic Woman", while the last two, "X-Ray Creature" and "Dinghy Days" are the A-side and B-side of Marc Hunter's first solo single released in 1973.
