What have you forgotten to take to a gig?
Prompted by our last gig where we suddenly realised we didn't have the mixing desk. Fortunately the pub is very near my house just the other side of the railway crossing, yup you guessed it I had to wait 7 minutes for the freaking train to pass. How did I forget well the house was at 6s & 7s as my sister was over for Xmas with her mental dog (a large Munsterlander). My mrs wasn't too impressed as she sat with the dog which howled all night. Our kid enjoyed the gig though and got chatted up several times including getting offered charley (not something you should offer a senior operating theatre sister).
Don't touch that dial.
