The Doobie Brothers are hitting the road for their 50th anniversary and have just added more tour dates. The group announced that they have added August tour dates in Milwaukee, Green Bay, and in Moline, Illinois. Michael McDonald will be joining Doobie Brothers for the tour, which will be the first time in 25 years. “We are looking forward to finally getting back on the road to see our fans and formally celebrate our 50th anniversary,” singer and guitarist Tom Johnston said in a statement. “Following this past year, coming together to celebrate our anniversary makes it even more special.” No word yet on a Utah date, but we will let you know!
