Michael Cassavitis (b. 1944) started singing doo-wop, recorded a few small hits, and then ended up as a vice president at CBS Records. But he couldn’t get the showbiz bug out of his system. Over the years he formed Wind, which had one hit in 1969, and then he hit the jackpot with Dawn in the Seventies.
When I covered the songbook of Brill Building composers Barry Mann and Cynthia Weil, this song figured prominently.
