Just found out that tonights gig is a 'ticket do' so in order to attend there are one or two options:-
1. Offer to buy a ticket at the door.
2. Blag about being a special guest of the band and entitled to special entry price.
3. Agent needing to be there for vetting of the band for future gigs and, again, requiring reduced (or free) entry.
4. Pose as road crew - this would involve you (and presumably Mrs. SF) dressing in baggy combat shorts (regardless of climate), wearing old black T-shirts carrying 'gear' logo (usually Marshall or Zildjian), tool bag/belt (with nothing of any use), a degree of facial hair which does not quite equal a proper beard or 'tach, and of course a pony tail.
Good luck.
