It's a bit of a mixed bag. I'm not sure I'd call The Beatles a boyband in the Westshoite meaning of the word. 
I do not want to see Honey G jumping

I think 4oD might do a reasonable jog of 'Hold On'.
I have visions of Elfish with a host of Elfish clones in a scary ott Girls Aloud version of the video.
(which, wierdly, I was telling ds , was number one the week he was born. Christmas 2002).
Off to a firework display, having only just warmed up from watching dd1 play football this morning. See y'all later, possibly a bit late.
