"How many you guys actually drunk right now?" Thundercat asked a packed Mojave Tent crowd. As heard on his recent cosmic-funk opus Drunk, the singer-bassist has a knack for wild combinations. He interrupted his 50-minute set to introduce a very unlikely Coachella performer: Eighties hitmaker and blue-eyed soul man Michael McDonald. The pop crooner sat behind a keyboard and together they recreated "Show You the Way" (which, on Drunk, also includes McDonald contemporary Kenny Loggins), as Thundercat stepped back from the mic with a smile. If a lot of the younger fans watching couldn't quite place the McDonald name, there was was a lot more recognition when the singer dove into "What a Fool Believes," his massive radio hit with the Doobie Brothers.
