For those who remember the 70’s and 80’s BBC 2 music programme :-
According to presenter Bob Harris, the programme derived its name from a Tin Pan Alley phrase from years before. When they got the first pressing of a record they would play it to people they called the old greys—doormen in grey suits. The songs they could remember and whistle, having heard it just once or twice, had passed the old grey whistle test.
Many a now-famous face were given their first 15 minutes of fame on the “Old Grey Whistle Test” and we have it to thank for introducing vast quantities of quality music to the record buying public.
This is not the real logo folks, as I believe the original is copyrighted, and this was created with Microsoft Paint and GIMP. My stars are blue instead of grey splodges, and my font and colours are different.
