Today?

Not just yet.

Every Monday morning I go in to Raglan Primary School and do an assembly.

We normally do lively songs. There's one I like at the moment with the action of a submarine submerging. Don't ask.

This morning, I decided to have a dry run for Wednesday afternoon when I have to sing live on the Roy Noble show on BBC Radio Wales.

So, I asked if they knew what busking was - they did. I asked who the greatest living songwriter is but they didn't know. Fortunately, one of the staff did, so I sang Blowin in the Wind and Streets of London. The, I made some point about war, homelessness and people's indifference to the problems of others.

I got the staff to pretend to be passers-by and they did a good job, making encouraging remarks, not paying any attention and sometimes pretending to throw money.

Anyway, I glanced into my guitar case - great: full of money! Twenty pence pieces and fifty pences mainly.

Then, when I came to put my guitar away, what a let down . . . PLASTIC MONEY.

Well, that's primary schools for you.
