Corn Mo (born Jon Cunningham) is a solo act who performs with an accordion and an upside-down high-hat cymbal placed strategically on the floor which he hits with a drum stick jammed in his shoe laces. He is originally from Denton, Texas, and currently living in Brooklyn, and first opened for TMBG on 05-22-2003 at the Bowery Ballroom in New York City. He claims to have been inspired by They Might Be Giants to play accordion and become a musician. Sometimes he performs with his band, .357 Lover.
In 2004, he performed with They Might Be Giants on Particle Man (called Particle Mo at many of shows along the Spine On The Highway Tour). He also joined TMBG for a rendition of Focus's Hocus Pocus several times in 2005. His song "Lollipop" appeared in Podcast 7A.
