On one of our many trips out, we were sat in a cafe, supping tea and discussing various letter-themed tunes that we could install on our mobile phones - just to use for an alert for any incoming text messages. I know; sad, isn't it? The usual suspects turned up pretty quickly - The Proclaimers' "Letter From America" and The Carpenters' "Please Mr. Postman".
It didn't take long before we fell quiet, having run out of obvious choices, but then Julie threw something in that was so left-field it was positively trippy.
"Oh dear," I thought, "It's going to be like that is it?"
