Surprise!

Phoebe Bridgers performs live from Forest Hills Stadium on WFUV tonight. MUNA is also on the bill and we hear there may be a surprise guest, too. So here's our question this morning: who have you seen as a surprise guest in concert? Tell us who was on the bill and who was the surprise guest. We'll bring them on just after 9 a.m.

Here's what we played:

David Byrne "Dirty Old Town"

The Police "Driven to Tears"

Joan Osborne "Ladder"

10,000 Maniacs with Michael Stipe "To Sir with Love"
