I was just watching a video about the most successful yacht rock singer that no one has ever heard of, even though you've heard a lot of his songs. He was featured on the Professor of Rock, I believe. He had 8 hits in the 70s and 80s, but I'd never heard of him before I watched that video, probably because he didn't like touring and rarely performed anywhere but in the studio.
Some of you may have heard of Paul Davis, but he was new to me, even though I know a lot of his songs. According to the video I watched, he was more of a songwriter and preferred that to actually performing, but he had a voice for singing yacht rock, which wasn't called that back then.
Some of his hits included Cool Night, I Go Crazy, Sweet Life and 65 Love Affair. He also crossed over into country and had two hits as a guest vocalist on songs by Marie Osmond and Tanya Tucker. His biggest hit, country or rock, reaching No. 4 in the U.S. in the adult contemporary category, was Ride 'Em Cowboy, which I'd never heard of before.
