Billy filled a place in the market that was almost impossible to achieve. A great professional and entertainer. I am sure a lot of the pundants of singers were jealous of his natural ability as well as his trained professialism.
Yes great voice, wonderful phrasing and i think really underrated. As i think nearly unknown outside of US. I got a wonderful record from 1974 "If she walked into my life". So sad it can not be played here in lastfm. I want a recording tool for records for lastfm. :-)
