"777-9311" is the second track and lead single from The Time's second album, What Time Is It?. Recorded for the album at Prince's home studio in May–June 1982, the song was produced, arranged, composed and performed by Prince with Morris Day later adding his lead vocals. "777-9311" reached number two on the R&B charts and number 88 on the pop charts. It is one of The Time's signature numbers and is played at nearly all of their concerts. A version recorded live in a 1998 concert segues from "Get It Up" and was included on Day's 2004 album, It's About Time.
