John Phillips from The Mamas & The Papas wrote this song. In the liner notes to his solo album Phillips 66 (where his version of the song appears), it states: "John often used to tell the story behind 'Me And My Uncle.' Years ago he began receiving publishing royalties from a song on a Judy Collins record with which he was unfamiliar. It was titled 'Me And My Uncle.' He called Judy to let her know of the mistake because he hadn't written any such song. She laughed and told him that about a year before, in Arizona after one of her concerts, they had a 'Tequila' night back at the hotel with Stephen Stills, Neil Young and a few others. They were running a blank cassette and John proceeded to write 'Me And My Uncle' on the spot. The next day, John woke up to the tequila sunrise with no recollection of the songwriting incident. Judy kept the cassette from that evening and then, without informing John, recorded the song for her own record. Over the years the song was recorded by several people, and eventually became a standard of the Grateful Dead. John used to joke that, little by little, with each royalty check, the memory of writing the song would come back to him."
