It’s our last Lollapalooza date, 19 years ago today, in Detroit. We invite our side-stage buddies, the Coctails, to help us say goodbye, sitting in on four songs. Last year, we dropped in on the United Kingdom for just as much time as it took us to lose a passport, play the Latitude festival, catch the end of Richard Thompson’s set, and find the passport. (Faster than you might think.)
