STOCKHOLM - Per Gessle and his Son of a Plumber project were guests at TV4's Nyhetsmorgon this morning. Son of a Plumber performed "Hey Mr DJ" live in an acoustic version and "I Have a Party in My Head" lipsynced. In the interview Per told the host nothing that TDR's readers already don't know. Although he did mention that there's a big chance Roxette will record something next year. "I'm not sitting here promising anything, though," Per said.
