I went out with a girl who's brother was best mates with the band and grew up with them, he was actually asked to be their manager when he was 18 and his dad said 'don't be daft son, these bands come and go and you've got a good job with BT'
He never regretted that then.
Anyway my then GF used to pick up her brother's laundry once a week and sometimes I'd go with her and sitting in his flat would be most of Iron Maiden.
I was never in to them but I remember telling a couple of mates who nearly wet themselves and kept asking me to get autographs etc but I thought it a bit rude to ask when they 'off duty'.
