"It's Unbelievable" was a hit for Philadelphia doo wop group The Larks in 1961.
The chance to record the song came about as a result of Weldon McDougal running into Atlantic Records promo man Jerry Ross.
[3] The group that played on the recording were called The Manhattans.
They consisted of drummer Norman Conners, sax player Harrison Scott, guitarist Johnny Stiles, and keyboardist Ruben Wright.
[4] Wright was formerly with Philadelphia group The Capris and had written their hit God Only Knows.
