I always think this is the Beatles & Paul singing
I now see the reason :The song was written and sung by Pete Ham and produced by George Harrison, who plays some of the slide guitar parts of the song along with Ham. The record also features Leon Russell on piano. As the song was unfinished at the time Harrison left the Badfinger album to produce the Concert for Bangladesh, the final mix was done by Todd Rundgren, who took over Straight Up after Harrison's departure.
