Two Man Acoustaoke
Apparently, the minimum space you need for a raucous Rockaoke gig is a Primary School classroom. Insert a block of staging, a hundred feet of black cloth and finish it off with a few sets of fairy lights. That gives you a cosy venue for 70 people. Then to make your party rock you just need to add 1 pa, two of the Rockaoke crew, 1 acoustic guitar, a bag of egg shakers and of course, a room of rock stars.
