Coming a little late to this thread I see my own unasked question was wonderfully and completely answered by one 'Rusty Dobro' back in August 2006! Whilst working for the illustrious firm of J.Murphy, Cable Contractors of Store Street, London back in 1973, one of my navvy colleagues, an Irish fellow rejoicing under the name of 'Tip' Delaney would suddenly, and for no imaginable reason save for the joy of being alive, break into the song "When I was a lad I was bicycle mad, I would ride between motorcars, and make no mistake I would put on the brake, without touching the handlebars". I urged him to sing more but that was all he could remember. I never discovered the rest of the lyrics, not, that is until now. What a resource this is!
