I spoke with Bob for several minutes last night and asked him about the chronology of his career.
He began dancing when he was in the Air Force and joined Arthur Murray in Texas after his discharge.
He became regional dance director for them before leaving to join Fred Astaire in Texas in the same capacity.
Eventually, he migrated to Atlanta with FA before eventually, as he put it, "giving up on the chains." He's been independent ever since.
Apparently, the chains had a stranglehold on the development of dance instructors in the US at that time.
I told Bob that you're currently in England and doing well. He sends you his best.
