A little while ago I blogged that a fellow MP mentioned he had seen Mamma Mia, told me I was in it (Donna) and I mentioned that I must now see it myself (especially as I'm supposedly in it).

This was enough for Iain Dale an Abba fan, who has obviously secretly been looking for any excuse, to book four tickets.

You know how Iain has a bit of a thing about lists, top ten political journos, that sort of thing, well I couldn't believe it when the first number struck up, Iain leaned over and whispered in my ear, “that's my second favourite!” His no. 1 is Winner Takes It All, which happens to be mine too.

It was the best show. By the end we were up singing and dancing and Iain’s partner took a photo of Iain and I dancing on my blackberry.

No, I wasn't dancing ON the blackberry, the picture is in it, and I'm not showing it to anyone.

Sorry if I sound secretive, however, to fellow MP who I know is watching out for blog report - OK, I give in, I did recognise myself!

If you haven't seen the show you must, great entertainment.

Thanks Iain, a lovely thing to do. Thank you for the music!
