Fifteen years before his 1981 hit “Jessie’s Girl” made him a household name, rocker Rick Springfield tried to commit suicide over his looks. He writes in his new memoir, “Late, Late at Night” (Simon & Schuster) that he tried to hang himself at age 17 when he felt “as ugly as the ass end of a female baboon at mating season.” He hung for about 20 seconds from a ceiling beam but miraculously, the noose undid itself. “From this point on, music will become my salvation and save me from most serious self-inflicted harm,” he writes.
