I'll never forget the day that I didn't meet singer Elvis Costello. It was a Saturday in Lerwick. Most Saturday afternoons I would go for a couple of pints at the Thule Bar, down by the harbour, with my flatmate Lois. But that Saturday there was an old film I'd always wanted to see showing on Channel 4. So, I didn't go that Saturday. Lois was a long long time coming back. When he finally did get home it turned out he'd spent the afternoon boozing with pop star Elvis Costello. Costello and his then wife were on a cruise ship that had called in to Shetland to let the passengers stretch their legs. Costello didn't get further than the Thule on the quayside.  Lois said he was good guy and had promised to come back to Shetland and play. And lo and behold, he did come and play at that year's Shetland Folk Festival. Just him and his guitar. If he hadn't already been a star, you would have said he was going to one. He was bigger and broader than I'd expected, the TV made him look a bit scrawny. I can't remember the name of that film that was on Channel 4.
