My mother used to listen to Grand Hotel - often while doing some ironing.
It was broadcast from a virtual 'Palm Court', and was gentle light music as one might have heard in, yes, a grand hotel, but minus the tinkle of tea-cups... A variety of violinists took the helm over the years - Tom Jenkins, Albert Sandler, Max Jaffa and the Pips,, and it must have been relayed to France, because the opening announcement would be repeated in that tongue.. 'Monsieurs et Madames, nous vous prions d'écouter une progamme de musique légère, interpreté par Tom Jenkins et son orchestre' - funny how things stick in your memory!
and the signature tune was a waltz, Roses From the South
I'll bet nobody remembers the morning programme that featured the Charlie Katz Novelty Sextet, with announcements by Tim Gudjin...
