I’ve got tons of these things on my hard drive, and really the ones on that website are pretty normal. A crate of premium lager and bottle of vodka/whiskey/rum are standard on most riders, as are towels (they often seem to want about 10 each for some reason). Other common items include lemons (I think singers eat/drink them before the show), odd food requests (I’m looking at one now that asks for 2 roast chickens and 2 cans of tuna) and incense (probably to mask the smell of weed).
