Ridiculous song credits

You nailed my last one (Abergavenny!) with no problem, can you identify this?

I don't even remember the song, but at the end (sounds like a live performance), he goes into a completely OTT list of performers. Starts normal (soandso on bass, keyboard, etc), but then goes into to oh, I don't remember, like, the Prince of Wales on whatever, and so on. I'm thinking it sounds like Zappa, but I just can't pin it. Any ideas for OTT and ridiculous credits?

Possibly "The Intro and the Outro" by the Bonzo Dog Doo Dah Band?

You are amazing. I don't think that's it, but now I get that what I'm remembering was probably a brilliant parody of that. The song I remember had a much more funky-jazz feel (really Zappa-ish). But if I never find it, I'm glad to have discovered the BONZO DOG (DOO-DAH) BAND - 'The Intro And The Outro'. Thank you
