Ah yes Helen, I did mean spitting it out onto the ground is a filthy habit, not actually chewing it!

I absolutely adored Lonnie Donegan when I was young. All his songs are excellent (My Old Man's A Dustman, Rock Island Line etc)

When I did Prison Visiting, I learned that DNA is used quite a lot to identify criminals (serious crimes that is) Amazing how a crook can be identified and the evidence strengthened. How Science has advanced!
