Singer Judy Collins released an album of duets entitled “Strangers Again” and Jimmy Buffett sings on the track “Someday Soon”.
In an interview in Digital Journal, Collins said the title track “Strangers Again” started it all for this project. “Then, I was working with Don McLean and I told him that I wanted to do a duets album, and he told me that he wanted to sing ‘Send In The Clowns’ with me. Then, I ran into Jimmy Buffett in the summer, and he said he wanted to sing ‘Someday Soon’ with me, and those three songs had me going,” she said.
