Robin Geoffrey Cable was Trident Studios’ house engineer, in 1972.

Cable was experimenting with re-creating the "Wall of Sound" style favored by Phil Spector. He recorded cover versions of the following two songs:

• "I Can Hear Music" (written by Jeff Barry, Ellie Greenwich and Phil Spector, which had been a hit for The Ronettes and The Beach Boys)

• "Goin' Back" (written by Carole King and Gerry Goffin, which had been a hit for Dusty Springfield).

Cable enlisted Freddie Mercury to perform lead vocals on these tracks. (Queen were recording their debut album in Trident Studios at the time.) Mercury in turn suggested bringing his band-mates Roger Taylor and Brian May to add percussion, guitar and backing vocals to the recordings.

The tracks were released as a 7" vinyl single on EMI in 1973, but failed to chart.
