Gregg Sinclair who - as I mentioned previously - was a panel operator at 2GB, emailed with two more examples of Timeout Instrumentals: Lapland by The Baltimore & Ohio Marching Band (1967) and Hot Pot by The Tornados (1964).
Lapland is one of those obscure instrumentals that was surprisingly popular in Australia. In early 1968, it reached #5 in Sydney, #20 Melbourne, #9 Brisbane, #20 Adelaide. It didn't register nationally in the US, but charted regionally.
As for The Tornados: I can't believe I overlooked them, as they would've been a rich source of Timeout Instrumentals. They had that one stunning worldwide hit with Telstar (1962), produced by Joe Meek who also wrote a lot of their tracks, and they continued with a series of organ-led instros. These were pleasant enough but not in the same class as Telstar, and tended to sneak into the lukewarm end of the hottest hits.
Globetrotter (1962), Robot (1963), Dragonfly (1963), Monte Carlo (1964), Hot Pot (1964) and Exodus (1964) all charted somewhere in Australia - though not spectacularly - and I remember The Ice Cream Man getting some airplay as well. One thing Aussies dug in those days was an instrumental.
The Tornados. Bassist Heinz Burt (far right) had some vocal hits as 'Heinz', notably Just Like Eddie (1963)
