Iron Maiden wasn't just a hard rocking band, they were also partying way harder than any other legendary band ... according to their drummer, Nicko McBrain.
Nicko was outside NBC in NYC when he got all nostalgic about Maiden's more than 40 years of touring and, no doubt, destroying a hotel room or two. When we asked him if anyone came close to keeping pace in the partying department ... he gave props to some L.A. based rockers.
BTW, to Nicko's point -- Iron Maiden's still rocking while the L.A. guys are retired. For now.
