I can hear tiny footsteps in my head

Back again, after a small flurry of activity and a hugely painful, close to incapacitating back pain, which is now on the wane. Hoorah! And...Phew! Didn't fancy having to go and get it "looked" at. Here's another Hi-Fi Choice illustration, I'm guessing it was something to do with sound and emotion but I can't recall exactly what the column was about. All I remember is being asked to have Numskull type characters in it. I don't know if they're still in The Beano but they used to be in it when I were a wee lad.
