I have got 3 generations of vocal on mine, lurksalittle loves it so far and I nearly whizzed myself on the first family run through .
I am waiting on some detailed feedback from my lad as he is more familiar with the genre, and as he 'sang' it , I think it fair.
Ed to add , I've been given 1 suggestion which is worth following up on , so I'll do that in the morning and get the thing published , I can start Christmas after that
