I believe he is supposed to be roadying for Status Quo.
This may be believeable for anyone who has never been backstage at the size of show Quo do these days - a man of Les's age would not get past first base - by his time of life he would either be in a senior position as a Tour Manager, or maybe running sound or lights, but a 'humper' of his age simply wouldn't stand the hours, the work, and the travelling.
Still, it is a soap so ...
we'll have to see how they write him out - maybe he'll fall off the back of a lorry ...!
