VIDEO: Andrew McMahon Performs with Relient K

The lead singer of Relient K, Matt Thisessen, was not feeling well in Australia during the Soundwave Festival recently — so Andrew McMahon to the rescue. What a pal!

A fan was able to snag a video of the Jack’s Mannequin singer, filling in on vocals for one of the band’s more recognized songs, “Be My Escape”. Cool to see bands helping each other out in a pinch! Relient K are also rumored to be working on a new album that should be out this Spring. Yay!
