1982: After cracking the Billboard Top 40 in 1980 with "Angel Say No", the four man Rock group from San Francisco named Tommy Tutone reached #5 with "867-5309 / Jenny". Lead singer Tommy Heath said that he really does know a girl named Jenny whose parent's phone number was 867-5309. Many folks with that phone number had it changed to avoid prank calls.
