I recently saw Buddy Guy in Toronto (my 3rd time seeing him). He visits the city on his annual tour. I also feel fortunate to have seen Stevie Ray Vaughn before his death. I had a ticket for John Lee Hooker but he took ill causing the tour to be postponed and ultimately cancelled due to his death.
Not to rain on everyone's parade, but I saw King in Toronto several years ago. Jeff Beck was the opener. It wasn't a very enjoyable night. The crowd had no real interest in Beck (I was there more to see him) and I wasn't really impressed with King's performance. I wasn't really familiar with his music, but have an open mind. I actually thought 1 of his back up guitarists was better.
