Paul Hamilton Williams (born September 19, 1940 in Omaha, Nebraska) is an American musician, composer, songwriter and actor.
Williams is responsible for a number of enduring pop hits from the 1970s, including a number of hits for Three Dog Night (including An Old Fashioned Love Song, "The Family of Man", and "Out in the Country"), Helen Reddy ("You and Me Against the World"), and The Carpenters, most notably "Rainy Days and Mondays," "I Won't Last a Day Without You," and "We've Only Just Begun", which has since become a cover-band standard and de rigueur for weddings throughout North America. An early collaboration with Roger Nichols, "Someday Man", was covered by The Monkees (a group for which he auditioned but was not cast ) on a 1969 single, and was the first Monkees' release not published by Screen Gems.
A frequent cowriter of Williams was musician Kenneth Ascher; their songs together included the popular children's favorite "The Rainbow Connection", sung by Kermit the Frog in The Muppet Movie. Most recently, he collaborated with Scissor Sisters on their second album, Ta-Dah.
Williams has worked on the music of a number of films, including writing and singing on Phantom of the Paradise (in which he also starred) and Bugsy Malone. He wrote the music for a musical production of Happy Days that debuted in 2007.
