Other web sites will tell you that the Invincibles were a vocal group from Los Angeles who specialised in the falsetto style of singing which was so popular from the late 50s to the early 70s. By the sixties a group called The Invincibles had the members David Richardson, Lester Johnson and Clifton Knight, and their records fitted that description, but it is not known if that is the same group as on this earlier recording which was issued by Chess in 1959. The sixties Invincibles group was not very successful, and folded. “Moonglow” is a typical late 1950s doo-wop group recording. I note that there are four composer credits on the label and these might or might not be group members – the names appear to be Hansen, Brown, Gretzia and Goode – in which case this recording is by a different Invincibles. Can anyone shed any further light please.
