Chords - Sh Boom

The Chords -- Carl and Claude Feaster (lead and baritone), Jimmy Keyes (first tenor), Floyd "Buddy" McRae (second tenor), and Ricky Edwards (bass) -- formed in 1951 in the Bronx, but weren't discovered until three years later, when they were spotted singing in a subway station, a performance that ultimately landed them a recording contract with Atlantic Records.

Jerry Wexler, Atlantic's top talent A&R man, had the Chords cover a Patti Page hit, "Cross Over the Bridge" (it was also covered by the Flamingos for Chance), but it was the B-side, "Sh-Boom," a swinging R&B vocal tune with a catchy intro made up of seemingly nonsensical syllables ("shh-boom, shh-boom, yadda da da yadda da da da da da") that caused considerably more commotion.
