Yes, I earned it for the scouts, but this was 1981 when it would have taken 10 jobs to earn the £1.67 I got from the shed demolition. The going rate was about 50p an hour for child labour back then.
Pound for pound, I think the most satisfying money I've earned in my life was as a scout during bob-a-job week where me and two friends were given a fiver to dismantle a wooden shed with hand axes.
We would have been about 13 or 14 tops. No goggles, no gloves.
