Spook speaks quietly

The Old Grey Whistle Test (usually abbreviated to Whistle Test or OGWT) was an influential BBC2 television music show that ran from 1971 to 1987. According to presenter Bob Harris, the programme derived its name from

… a ‘tin pan alley’ phrase from years ago. 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 ones they could remember and could whistle having heard it just once or twice had passed the old grey whistle test.^[1]
