Rich Cronin, best known for being a singer in the boy band LFO, has died after a battle with leukemia. LFO had several hits, including “Summer Girls” (see below) and “Girl On TV” (which was reportedly inspired by Cronin’s real-life relationship with actress Jennifer Love Hewitt). He also appeared on the short-lived Vh1 reality show Mission: Man Band, which featured former boy band members, including ‘N Sync’s Chris Kirkpatrick, trying to form a new adult group. Cronin was thirty-five.
