"Monkberry Moon Delight" is an album track off of "Ram" 1971." Paul goes for a sort of hillbilly sound on this one, doing strange things with his voice. If you didn't know it was a Paul song, it would be difficult to figure it out just from the track. Linda contributes some outstanding backing vocals along with their daughter Heather.
Paul and Linda recorded "Monkberry Moon Delight" between 12 October and 20 November 1970 at CBS Studios in New York City, and final mixing was done at Sound Recorders in Los Angeles shortly thereafter. Paul says that he likes "Monkberry Moon Delight," but he never sings it live - probably because it would be impossible for him to sing it live with all the vocal gymnastics that are required.
"Monkberry Moon Delight" is a secret pleasure for many Paul McCartney fans. It has a completely different sound than virtually any other song he's ever done, a sort of "Rocky Raccoon" by a mountain man on cocaine. I'd certainly rather listen to it than to "Yesterday" for the 1000th time.
