Career Lopez made his name on the club circuit of the Southwestern United States before being 'discovered' in 1962 playing at the club PJ's in Hollywood, California, by record producer Don Costa. Costa was taken with Lopez's latinized versions of contemporary hits and signed him up to Frank Sinatra's record label, Reprise Records. His debut album, Trini Lopez Live at PJ's, was released in 1963. The album included a version of "If I Had a Hammer", which reached number one in 36 countries (No. 3 in the United States) and was a radio favorite for many years.
