Nice but sorry Kathy. There is only one Terry Kath, the original Chicago Transit Authority lead singer, (one of the three), The greatest lead guitar player ever, but that guy in this video is not him. Good player tho.
I don’t know him or the group....you are stuck with youtube. I’ll go look around.
How about this one?
