I saw Long John Baldry with Rod Stewart above a garage in Derby around 1965 - it was brilliant. I also saw the Walker Brothers in Derby around the same time.
I saw Gene Pitney a few times and loves 24 Hours from Tulsa.
We have seen Meatloaf about 6 times and wish I had seen Jonny Cash. I love Kris Kristofferson
I've got another 'keen'... Ouch!
