Hi maggiemae,
People use different terms but they're usually talking about different things. A backstage pass would mean that you could be backstage while the show was 'on stage', very rare. After the show Gordon & the band 'meet & greet' in the backstage area, after the show. For that you'll need to get on 'the list' (email Barry) and make your case. If the list that night is small hanging around with people who look like they're waiting to be shown backstage i.e. they're on the list - might work. Looking pretty never hurts.
As for waiting in the alley or by the backdoor, anyone can do that, obviously, but you have to wait while the meet & greet is going on - usually at least an hour or so.
Maybe someone who REALLY knows the ropes will private message you some tips. Good luck and enjoy the show.
Bill
