soooo how long will it take

Anyone know how long it usually takes to make a dvd from a concert? How long after Dolly's London concert did Live from London come out on DVD?
It's so quiet around here now eccept for all the spamming blogs, i can't remember what it was like before the tour started but i guess everyone is just moving on and waiting for the tour dvd to come out or waiting for Dolly's movie to come out....damn Australia.....i don't know if it willl even come out over here ><.......
you know what i think is great?...the fact that every member of Dolly's team like the singers and band members...they could all go out individually and be famous in their own right, yet they stay with Dolly, which is just amazing, the second concert i went too, i didn't often look at Dolly i was watching everyone else on stage lol and really they are all brilliant and i would watch them watching Dolly..... it was cool. I realise none of them including Dolly would hop onto this site at all but i really hope that they all know they are as big a part of the concerts as Dolly is.
Anyway...i think i've finnished rambling now. i hope everyone had a fantastic time at the concerts they went too!!
