Mentioned on here before - Rick Wakeman famously ate a full Indian meal.
"It was 1973 and we had released Tales from Topographic Oceans, which I didn't particularly like. The third piece in the show was a particularly long percussive piece and I didn't have much to do. Now, I used to have this roadie that worked for me, he would lie underneath my keyboard ostensibly to fix things, but mostly he would just mix me drinks and pass them up. So on this occasion he asks me if there's anything I need, but I heard it as him asking what I felt like doing after the show. I just replied 'oh, I'll probably go for a curry' and then he asked me what I would have so I started naming various menu items, 'onion bhaji', you know...and then, 20 minutes later there is this smell. Of course you know that curry is a smell that wafts, you detect it. And he's standing there under the keyboard rig with these bags of takeaway curry."
The story, a classic pull-the-other-one, is "absolutely true". And Wakeman says he proceeded to "lay out the meal across my keyboards to have some." If you are thinking Spinal Tap right now, remember this is 10 years before that film. And Wakeman chuckles as he adds the coda, "I've probably been offered curry at gigs a couple of dozen times since, I don't have it on stage, but I'll arrive backstage to find that someone's sent a takeaway curry to me, or it's been ordered, or there's a takeout menu there. It's nice. It's funny.
