Chesney Hawkes had one huge number one hit "One and Only" which stayed at the top of the charts for ages (I think it was about 7 weeks). I remember he also released another single "I'm a man and not a boy" but it didn't do anything like as well.
Chesney, at that time, appeared in the TV series "Buddy" with Roger Daltrey playing his teddy-boy dad.
