"My Maria" is a song co-written by #BWStevenson and #DanielMoore. Lindy Blaskey, a music publisher at ABC/Dunhill Records, thought Moore had a possible hit with his verse and chorus, but could not get him to finish the song, so Blaskey took what Moore had so far and asked Stevenson to finish writing it with an additional verse. David Kershenbaum, Stevenson's producer at RCA, agreed with Blaskey that it sounded like a hit and produced.
