I hope the DVD says which night the performances are from. I thought HTCT was a killer song to open with...honestly the BEST opener!!! It was one of my favorite concerts seeing these 2 guys together after all these years...when the lights went down, I didn't feel like I was in a big arena at all, let alone MSG.
And if I've said it once, I've said it a thousand times...it still blows my mind that Joe Bonamassa is the main artist that ever covered this song, no one else really ever brought this song to the forefront after Blind Faith. So, 35 years after it was recorded the classic riff and song are covered by Joe...just awesome!! And, honestly I love both versions, growing up with the original and loving Joe for showing such respect to a classic...for what its worth!! 
Can't wait for the DVD to arrive!
