I've seen many Santana concerts. I'm a big fan.
That said, he's not close to being as good as he used to be.
I just want to see the greats before they are retired or gone, even if they arent as good as they were 40 to 50 years ago.
I have managed to catch quite a few the last 10 years (Eagles, Chicago, The Who, ELO, to name a few). I missed seeing Bob Seger before he retired and I regretted it because I had the chance the year before that.
