Gig Venue

I'v been thinking if I'm going to convert the globe theater into a live music venue what important elements i'm going to have to add to the structure, heres the list:

lighting rig( how will this fit to the stage and structure?)

Audio equipment (pa system, floor monitors etc)

Audio Mixing (where will the sound booth be?)

type of roofing needed to be added ( if it rains gigs will suck in an open top arena and thats more than likely in London)

i'm going to have to redesign the stage for security purposes a little

and most importantly where to place the bar (every venue has one, theres no getting round it)
