The Doobie Brothers are celebrating their 50th anniversary with a Las Vegas residency, beginning in Feb., and then going on tour in June.

Of special interest to fans is that Michael McDonald, who hasn’t toured with the group for almost 25 years, will be performing.

The group includes two original members, Tom Johnston and Patrick Simmons. Singer/songwriter, guitarist and all around musician John McFee joined 40-years ago this year.

Tickets for the tour go on sale today.
