Paul McCartney, Club Sandwich interview, 1994:
Q: What’s the story behind a song called “Penina” which I believe you wrote for a Portugese band leader in 1968? Might you ever record it yourself?
A: I went to Portugal on holiday and returned to the hotel one night slightly the worse for a few drinks. There was a band playing and I ended up on the drums. The hotel was called Penina, I made up a song with that name, someone made enquiries about it and I gave it to them. And, no, I shouldn’t think I’d ever record it myself!
