There are citations about Tempo all over the internet - usually in relation to the various hosts like Philbin, Dornan, and Maria Cole
Apparently, RKO General (then-owned of KHJ-9) had "Tempo" shows on all it's local TV stations. Around 1969, there was a "Tempo" show on WNAC-7 here in Boston that was hosted by of all people, Dave Garroway (making a TV comeback; I believe he lived on Cape Cod at the time).
WNAC hoped that the show would eventually go into national syndication, but it didn't get enough of a following locally to interest either RKO General or any other distributor in syndicating it.
