Wait. HOLD UP! NO, I'm not referring to the millennials' favorite '90s pop vocal group, the Backstreet Boys; rather, I'm talkin' 'bout the other group of cherub-faced boys who ALSO happened to have been called the Back Street Boys! They were a mid-'60s beat group from New England and, I think, were the FIRST group of fellers to call themselves the Back Street Boys; "Back St. Blue," is their only known recording.

Unlike the contemporary Backstreet Boys, the '60s Back Street Boys obviously, and thankfully, chose to avoid harmonies altogether.
