From MOJO:

As much as the band could try to block out their disquietingly exotic environment during studio hours, any attempt to cut loose during their downtime only served to remind them of just how far they were from home. One night the party decided to visit Fela Kuti’s Afrika Shrine club to watch the Nigerian bandleader perform with Africa ‘70 and Paul, heavily stoned on the potent local weed, suddenly felt hopelessly out of his depth. 

“We got a bit over-wasted,” he says. “And I then got the screaming paranoias, suddenly being in this place on the outskirts of Lagos with absolutely no one we knew. Fela came off very much as a tribal leader and when he went on-stage he wore nothing except a grass skirt, which added to the impression (laughs). Had I have see a cauldron wheeled out with hot water in it, I would not have been surprised. But the release from that paranoia the minute his band played the first note was so overwhelming that I remember weeping. It was like ‘Wow.’”

But Kuti was suspicious of McCartney’s motives in Nigeria and mounted a local media campaign accusing the former Beatle of being there to filch elements of Nigerian music.

Amazing.
