CBS was battling RCA Victor at that time...even to the extent of promoting
their "LP" against RCA's "45!" This rivalry extended to the (short-lived)
33.3 7" single...?! If CBS ever issued 7" 78's at that time, I have NEVER
seen an example...did this post refer to CBS's 7" LP's?!

I have at least one of the 7" LP-speed discs...!
