Back in 1980 you could send off for a wall planner if you bought a packet of Surf. Or maybe Persil. Anyway it came with a 7" single. On one side Procol Harum sang A Whiter Shade of Pale. On the side Noel Edmonds explained what the wall planner was for and then some session singers, in the style of ABBA, sang the song "The Day They Remembered".
