Jo Jo said she found a cart of beans
Sold in a market down in New Orleans

The story:

During the thick of my Stones phase I'd Mick-mimed my meaningless, ninnified, version among friends countless times before I read the lyrics in my boyfriend's chord book. I'd even gone around wondering if the Jo Jo in "Get Back" was the same who found these beans...wasted a lot of time wondering who Jo Jo was and over-validating the finding of beans in a cart.
