Godfrey's morning show was supplemented by a primetime variety show, "Arthur Godfrey's Talent Scouts," broadcasting from the CBS Studio Building at 49 East 52nd Street where he had his main office. This variety show, a showcase for rising young performers, was a slight variation of CBS's successful "Original Amateur Hour". Some of the performers had made public appearances in their home towns and were recommended to Godfrey by friends or colleagues. These "sponsors" would accompany the performers to the broadcast and introduce them to Godfrey on the air. Two acts from the same 1948 broadcast were Wally Cox and The Chordettes. Both were big hits that night, and both were signed to recording contracts. Godfrey took special interest in The Chordettes, who sang his kind of barbershop-quartet harmony, and he soon made them part of his broadcasting and recording "family". Godfrey was also known for extemporizing music on the show, grabbing his ukulele and launching into songs the band may not have rehearsed. He had insisted on employing musicians in his small orchestra who would be able to accompany him quickly and "follow" him as he sang. This resulted in impromptu jam sessions on some broadcasts, rarely heard on mainstream variety programs.
