It's from "Summer Magic!" I had to check my CD collection (I have a recording of the song!), but sure enough that's what it is! LOL!
New Lyrics:
"Now as the ladder of life has been strung,
you might think a sweep's on the bottom-most rung.
Though I spends me time in the ashes an' smoke,
in this whole wide world there's no 'appier bloke."
One again I think I used a quote with a couple of hints, but there it is, enjoy!
Until next time (at the mic),
John
