Question: Were both of the singers that were also mentioned as individuals following the fad of releasing disco records born in the United States? Passage:"My Father's Song" was released as the album's lead single in August 1975. The 7" record was released in the United States and Spain where the song was retitled "La Cancion de Mi Padre". The song was paired with B-side "By the Way", although in Spain the track was titled "Da Paso". The single enjoyed success on the United States Adult Contemporary chart, where it peaked at numbers 11. It also entered the similar chart in Canada, where it reached number 15. Nicky Siano, a disc jockey, began playing Streisand's version of "Shake Me, Wake Me (When It's Over)" at The Gallery nightclub in New York City in the fall of 1975; in a handwritten letter by Streisand for Siano, she wrote that the hype generated from playing her cover at the club prompted Columbia Records to release it as another single from Lazy Afternoon. It was distributed in 7" and 12" vinyl formats on November 12, 1975 featuring the B-side and album track "Widescreen". A British version of the single was also created and features the longer cut of the single instead of the album version. Streisand's cover was noted by writers for Billboard as an attempt for pop singers to begin "releasing disco records"; other singers like Andy Williams and Ethel Merman were also mentioned as individuals following the fad. Due to heavy airplay in dance clubs, it entered two of the dance charts compiled by Billboard; it peaked at number 14 on the Dance Club Songs chart and number 10 on the Disco Singles chart.
