In 1977, Warner Bros. Music decided to form a special label, Pacific Records, for their composers who also performed. O’Day was the first artist signed, and his first release was “Undercover Angel.” The original vinyl pressing was released with the B-side “Just You”.
The song, which O’Day described as a “nocturnal novelette”, was released without fanfare in February 1977. Within a few months, it had reached #1 in the U.S., even without an album to support it. O’Day said of the experience, “It’s wonderful when you find out what feels right, and then it also feels right to other people. That’s a songwriter’s dream.” O’Day had also composed “Angie Baby”, a #1 hit for Helen Reddy; “Undercover Angel” thus landed him in a very exclusive club of singer/songwriters who wrote a chart-topper for themselves and one for another artist.
