John Salmon is not working anymore as far as I know, last I heard he was still suffering from the effects of the fall and will probably never work again. He had been the local window cleaner for over 20 years and everybody know him.
He fell getting back on his ladder from a flat roof in Mount Pleasant, Ruislip and suffered head injuries. He's lucky to be alive.
As for Gary and his wife, they just vanished. I heard he fell and broke his leg. Then his wife took over some of the round for a while but then she couldn't get on with the squeegee and used something she got from the supermarket. (Mr Muscle or similar). If I took you round my customers today you can still tell the windows she cleaned. They bead like mad, even after several years.
