Paul Williams composed "An Old Fashioned Love Song" (Paul Williams) specifically for The Carpenters and Richard rejected the song. You'll find this on Paul's 1971 album "Just An Old Fashioned Love Song". According to Songfacts Paul Williams said "I had a date one night, a young lady named Patti Dahlstrom, she was a songwriter. We were going to go out and have dinner. And right before I left for the date I had gotten a phone call that I had a gold record. And I walked into her house, and I said, 'Well, got a gold record for such-and-such, it just went gold. Kid did it again with another old fashioned love song.' It just came out of me. And I went, wait a minute. I went over to her piano and I sat down, and it's the quickest I ever had a song come out of me. And it sounds like it. It's a really simple song, I wrote it in like 20 minutes. And it was a big hit."
Chuck Negron and Three Dog Night's cover is from the 1971 album "Harmony". The single reached number four and topped the Easy Listening chart.
