For decades, part of a vaguely remembered TV commercial jingle has come to mind. I still don't remember what was being promoted, however. I have a hazy recollection of people dancing and singing, "That's what we're doing now in 1979!" The commercial's underscoring reminded me somewhat of the R&B hit, "T.S.O.P." by MFSB. It might have been a car dealership promoting its new line of vehicles. It could have been a theater chain touting its upcoming movies. Or, and I suspect this is most likely, it might have been a TV network promoting its new Fall shows.
While I'll live without knowing the particulars, I'd like to solve this decades-long mystery.
