STATUS QUO - ABC -> A
A Mess of Blues: the original song of this cover was from Elvis Presley way back in 1960. QUO's version was released in 1983 on the album "Back to back" and released as a single too. In Argentina this song was B-side of "Marguerita Time".
Almost but not quite there: The only single released under the band name "Traffic Jam" in 1967. The song soon was banned from the BBC playlist, because the lyrics were too "sexual" at the time.

ARSIS: This shortening can be found on some record covers. (e.g. recorded in ARSIS) It stands for "A Roof somewhere in Surrey". It is Francis Rossi's own studio.
