I don't think Michael McDonald tours with the Doobies anymore. I saw the Doobie Bros a couple of years or so ago and the only ones left from the original band was Tom Johnston and Pat Simmons plus John Mcfee who has been in the band since the 80s.
Jethro Tull is the next night. However I believe it will not involve Martin Barre, and if you have not noticed Ian Anderson now has another guy doing a ton of singing.
Just an FYI if that is important to you.
