"Avalon" is a popular song. It was written by Al Jolson, Buddy DeSylva and Vincent Rose in 1920. It was first recorded by Jolson and used in the musicals "Sinbad" and "Bombo". Jolson's version became #2 on the American singles chart. It is possible that Rose wrote the song alone, and that Jolson's name was used in the credits because he was a popular artist and helped make the song popular. At first only Rose and Jolson were marked as the writers, and DeSylva's name was added later.
