In 1984, Rockwell had his biggest single, "Somebody's Watching Me", with childhood friend Michael Jackson singing the chorus lyrics and Jermaine Jackson singing back-up. "Somebody's Watching Me" became a Gold-certified million selling #2 song in the US, which also peaked at #6 in the UK. It held #1 on Billboard's R&B chart for five weeks. Follow-up singles underperformed, with "Obscene Phone Caller" being Rockwell's only other Top 40 single. It reached #35 on the Billboard Hot 100. Rockwell released two more albums before ending his musical career with Motown.
