Here is info on the lead singer courtesy of Fred Clemens from the Oldies Music Message Board: "Lead on the Belmonts by then (your Sabina 507 posting), Spencer, was Frank Lyndon who had replaced Carlo Mastrangelo. Fred was still in the background throughout most of the Belmonts years, he being the only common denominator of the group since their first recording in 1957 on the Mohawk label."
