I think anyone who totally works alone - respect. I used to work alone until a rather 'sad' incident in Brighton a few years ago.
I use a number of roadies on rotation.
They get picked up and entertained via 'beer money', but I would not be without them.
Unlike a typical 'roadie', they are licenced as 'supervisors' and carry first aid certificates.
The most important thing for inviting these gentlemen along, for my peace of mind, is to literally protect my gear and assist in lugging it out safely at the end of the night.
Since the 'Brighton' incident - there has been only a handful of 'crowd incidents' and I'm glad to say we (roadie & I) were not heavily involved.
That said - if any of my guys takes a 'crack on the chin' as a result of either protecting my gear or supervising the safety of others near the gear - he gets a minimum 'bulls-eye!'
Apart from my resident venues where there are 'supervisors' employed legit to do this sort of work, I use 'Super Roadies' for 18th's, 21st's, 30th's AND 40th's.
And, they take requests which is great to allow me more time to concentrate on the gig.
Not everyone will agree with the way I work but the guys are pro's, don't need pampering and correcting.
O.K., they look like 'nutters' or 'muscle', but that's a deterrant!!!!
