Gary,
where are you from? Sounds like an Australian voice though it could be a Nu Zilund accent as well - that ones hard to detect in song.
The blues is cool - senior shuffle is always a good place for a laugh.
The vocals are pretty good, there's almost no sibilance and no age whistle.
Good one.

Cheers
