Boomer Castleman had a solo hit in `75 with his song "Judy Mae" (a sordid little story song involving quasi-incest and suicide). He also had written "What Am I Doin' Hangin' `Round?" for the Monkees with Michael Martin Murphey. He also invented the Bigsby PalmPedal, a steel guitar-like string bending device for electric and acoustic guitars.
