Thank you Ian for the translation.
Indeed, Glen is the world famous rhyming slang for Bondo - Wag - Body Filler etc and as I am yer actual Cockney born within the sound of Bow Bells, I feel eminently qualified, and indeed justified!, to exercise my birth right. I am not, however, Dick Van Dyke ( and before you ask, no, that is not rhyming slang....)
