Chicago

When a summertime trek with the Doobie Brothers kicks off later this year, Chicago will bring an extra milestone to the stage in addition to their legendary catalog of horn-driven classics: the versatile band is celebrating their 45th anniversary. And founding member and trumpet player Lee Loughnane tells Ultimate Classic Rock that the time has gone by in a “flash.”

The Doobie Brothers will celebrate their 40th anniversary as a group by teaming up with Chicago for a summer concert tour that will feature an evening full of hits from both bands and their legendary catalogs.
