Stage Invasion

Last night at Phibbers, a big punky lady spotted me from downstairs and came up to join in. She sat at the back, singing along loudly as soon as she'd picked up the gist. 'Can I jam with you?' she yelled over.
She made her way over to the stage area and joined me there. 'Can I jam with you?', she shouted again, lager glass in hand.
The promoter very gently coaxed her away and took her downstairs again.
I could hear her all the way through the rest of the set, bellowing away in the distance, still singing along at the top of her voice.
