Murphy is also a singer, having frequently provided background vocals to songs released by the Bus Boys; the song "(The Boys Are) Back in Town" was featured in "48 Hrs." and Murphy's comedy special "Eddie Murphy Delirious". As a solo artist, Murphy had two hit singles, "Party All the Time" (produced by Rick James) and "Put Your Mouth on Me" during the latter half of the 1980s. He had started singing earlier in his career, with the songs "Boogie in Your Butt" and "Enough Is Enough", the latter being a parody of Barbra Streisand's and Donna Summer's 1979 song, "No More Tears". Both songs appeared on his 1982 self-titled comedy album.
