If you have Comcast HD you might get this channel. HDNet is channel 707 on my system. In November (I think the 7th) it will be replaying the Live at the Ryman recording from 2007.
Comcast's new search feature now allows for keyword search. I searched "Vince Gill" and found it that way. I have it set to record on my DVR.
I hope you are able to get this. This is as close to a live recording as we might get. I would still love a live album.
