Written by Peter Udell and Gary Geld, this was first released in 1960 by the Four Voices but did not reach the charts. https://www.youtube.com/watch?v=nKGk9qg9A9k
Brian Hyland took it to No 3 in both America and Britain in 1962.
A terrible version by Gary Lewis and the Playboys got to No 19 in America in 1967.
Bobby Vinton arranged it for a 1972 release, inexplicably incorporating bongos. Despite this, it also reached No 19 in the US.
