"Hey Deanie" is a popular song by Shaun Cassidy that was released the last week of November, 1977 from his album, Born Late. It was his third and final top 10 hit, peaked at number seven for two weeks on the Billboard Hot 100, spending four months on the chart from late 1977 to early 1978. As with Cassidy's prior singles, this song also became a gold record. The song was written by Eric Carmen. "Hey Deanie" was the second hit written by Carmen for Cassidy, the first being "That's Rock 'n' Roll," from Cassidy's previous album. Both songs charted concurrently with Carmen's own hit, "She Did It". Carmen recorded "Hey Deanie" himself for his 1978 album, Change of Heart, and it was also featured as the B side of the title track's 45 RPM release, which became a Top 20 hit.
