"Nights on Broadway" reached number seven on the American Billboard Hot 100 singles chart, giving the Bee Gees back-to-back top 10 hits for the first time in seven years since 1968. Producer Arif Mardin asked if one of the Bee Gees member could do some screaming during the main chorus to make the song more exciting. In response, Barry Gibb began singing higher and higher, eventually singing it in a falsetto that was unexpectedly powerful. He had never known he had such an ability and Barry's falsetto became a trademark of the Bee Gees, Gibb recalled in a May 2001 interview with Mojo magazine "Arif said to me, "Can you scream?" I said, "under certain circumstances". He said, "Can you scream in tune?" I said, "well, I'll try"". The Beegees sound for the 1970's was set and the rest is history!
