I get a lot more texts than calls. Texts use the 'sting' from the end of 1970s/80s Newsround which I found - much to my joy - on a BBC Music and Movement LP which was about to be turned into a clock. It also contains a lot of other fantastic Radiophonic Workshop material by Delia and her pals.
My workmates - all around the same age - find it most nostalgic.
