I was crate digging at my local used vinyl emporium a little while ago and came across some sound effects records from the early ‘60s. Nothing amazing, until I checked the track list and noticed “Sounds of Football Match — ‘Block that Kick!’”
If you’re a Beatles fan like me, you’ll know what I suspected and then found to be true: I was holding the source of not just one, but several of the sound effects used in “Revolution 9” as well as the bird effects heard on “Across the Universe” and “Blackbird.” Apparently this must have been a popular disc at Abbey Road.
Now I mention this as a preamble to this amazing website by the BBC, in which they’ve opened their archive of 16,000 (technically 16,016) sound effects, many of which have surely been used over and over on various radio plays. (For the Americans out there, yes, BBC Radio still produces radio plays!)
