A singer-songwrtier who had two No. 1 hits has passed away at age 72, the Los Angeles Times reports.

One of the hits was a song sung by Helen Reddy. The other he sang himself.

Says the Times, “Alan O’Day, 72, who wrote popular songs for other artists, including Helen Reddy and the Righteous Brothers, but scored his own No. 1 single with ‘Undercover Angel’ in 1977, died Friday at his home in Westwood. The cause was cancer, according to his manager, Ken Kaufman.”

The Times obituary also says “Earlier, O’Day wrote ‘Rock and Roll Heaven,’ a popular song for the Righteous Brothers, ‘Train of Thought,’ recorded by Cher, ‘The Drum’ for Bobby Sherman and ‘Angie Baby,’ which was a No. 1 hit for Reddy in 1974.

The story also notes, “Born in Hollywood, O’Day grew up in the Coachella Valley area. He later divided his time between Nashville and Los Angeles.”
