I have to say, this is the best live version of Sour Girl I've heard! I like it better than the album. I think its Deleo's chords that bring the beauty of the song out! It has a cool groove to it!
Yeah - Sour Girl did sound particularly good. My fave version of it though is one of just Dean and Scott - no percussion, just the guitar melody and Scott's beautiful voice. It's kind of a rare version I guess - I've seen a radio performance of it on youtube, and I have it from years back on a rare, acoustic STP CD that I purchased on Ebay. I'd LOVE for them to maybe break out a song or 2 here and there with just Dean and Scott - let Robert and Eric have a smoke or a beer for a few songs while the other 2 just strip it down. I wouldn't be surprised to see that eventually, but I can see why they might opt not to do something like that at an all-day festival featuring primarily heavier bands.
This is probably also why they didn't do the whole extended acoustic middle-of-the-show mini-set that they've typically done in the past. I noticed that last night it was just Sour Girl and Creep for the slowed-down middle part of the show - and all the rest was rockin' out. Still great though.
I have a feeling that by the time this tour is all over, we'll have seen very many different combinations of songs, set vibes and overall types of performances. This is the perfect time - not bound by record label demands, not promoting new material - just out to relive the magic of their old music for the fans that love them. Can't wait, can't wait indeed.
