While working at ATV, he was asked to compose some music for Crossroads. Stephanie De-Sykes got to number 2 in the UK Singles Chart in 1974 with the subsequent "Born with a Smile on my Face", which was used within a storyline on the show. Almost a year later, her second single, "We'll Find Our Day" (from Smike) got to #17.
Kate Robbins performed another of May's songs for Crossroads: "More than in Love," which was co-written by Barry Leng and got to number 2 in 1981. May himself performed "Summer of my Life", charting at #7 in October 1976, though his follow-up, "We'll Gather Lilacs", flopped.
He co-produced Amii Stewart's "Knock On Wood", which reached number one in the USA.
