1950s doo-wop singers The Duprees will grace the Drew U concert Hall stage Sunday Feb. 16 at 3:00 in the afternoon. Sixty years on, they still sound good. Such songs as “You Belong To Me,” “My Own True Love,” “Have You Heard” and “Why Don’t You Believe Me” are such timeless classics that they deserve to be heard in a live setting; and Tommy Petillo (46 years in), Jimmy Spinelli (since 1989) and Shawn Stevens (the new guy) are just the voices to do it.
