They played an all accoustic set of all their songs which included songs from Spinal Tap but also songs from the movie A Mighty Wind, a movie about the folk singing genre. They're fabulous! Their harmonies were outstanding and they're excellent musicians.
They played for about a full two hours and were able to take small breaks by occasionally playing videos. They played a clip from Spinal Tap's first ever video that appeared on a show called The Tv Show in 1977 and a funny psuedo-documentary about cheese which featured Ed Begley Jr and a wee Jake Gyllenhall.
Which was trod upon by trolls.
They did one funny bit where they read comments by the network sensors about problem bits the movie Spinal Tap would have when played on network television. Apparently "We have armadillos in our trousers", a bit about a foil wrapped cucumber and the entire song Sex Farm were too much to show the audience at 11:30 at night.
