Paradoxical Undressing

I'm really looking forward to this:-

I'm not sure if the musical accompaniment is by K herself or takes the form of a backing track. Either way it should be an interesting show. I booked my ticket the other day. I'm two rows back (it's all seated) Janet to Carrie's side. I've booked a hotel but I'm wondering now whether to keep an eye out for any other shows in London the same week and maybe make it a trip for a few days. It's not 'till the end of March so I have a fair time to contemplate this one.
