"Brian and I originally wrote 'Some Sweet Day' together in the early Nineties for a movie," Paley told Rolling Stone in a statement. "The idea was that it would be sung by a female in the style of a Sixties girl-group like the Chiffons. It ultimately didn't end up getting recorded with a woman's voice but still I like the recording with Brian singing lead. That's Brian and me and my brother Jonathan singing the background parts. I'm playing one of the pianos, Brian's playing another one. I'm playing drums and guitar Jonathan's playing six-string bass. Brian hired a violinist and Michael Andreas played the woodwind part. It's a track that I've always been very proud of so I'm happy that people are finally able to hear it."
"I think it's a great song with good lyrics and a cool melody," Wilson adds.
