Rudy Lewis, the lead singer of The Drifters on their hits “On Broadway” and “Up On The Roof”, died under mysterious circumstances the night before the group was set to record “Under the Boardwalk”. He was 28 years old. Rather than reschedule the studio session to find a new front man, former Drifters backup singer Johnny Moore was brought back to perform lead vocals for the recording. The single reached #4 in the US the following July and #45 in the UK.
