Thanks - I actually remembered to get the DVD off Mum, though, so have now watched the (sadly few) minutes JB's in it three times... *g*

And yeah. This is going to be fun. Especially because I can't think about actually writing any of it till I've researched the era and the musicals and worked out which version of Jack this is... Which means I'm free to use the actual writing part of my brain on Master Plan (just started the next chapter).
