Thanks all.
Uncle Al - it's a Yamaha PSR1000 I'm afraid - superceded these days by several newer versions, but soooo versatile I've been able to live with it since 2001, and it still surprises me with its zillions of voice capabilities. All I can say is well done to the nice people at Yamaha. Having said that, I wouldn't mind getting my hands on a more recent offering from them. All donations much appreciated
The look I'm trying to achieve is one of plain semi-formality, with a touch of showbiz lightheartedness, and I feel it's almost there. The sporran is a problem and still harks back to a Scottish confusion. I might have a go at adapting one with a different front - maybe a sparkly musical graphic. Or, as my music is using modern technology, maybe I'll shape a circuit board and stick it on the front. That has a chromey maze on one side as a random hi-tech pattern (full of ideas!) and should catch the light as I sway sexily to the exotic rhythms

.
The audiences will be mainly elderly people who have seen it all in their lifetime, from Liberace affluence through Elton John eccentricity, to the dark suited, bow tied, theatre organist Reginald Dixon. So a little theatrical treatment to the sporran, with maybe a keyboard belt buckle would, I think, be a good way of visually saying I'm not taking myself
too seriously. Just so long as the overall look is neat, acceptable and memorable to ensure being invited back again.
I feel the long black socks are vital to the semi-formal look. The t shirt is an easy way of not having to decide what to wear up top every time. I'm going to be worried more about the accumulation of musical repertoire I need more than what clothes to wear.
Switching sides on the closures of women's wraparounds, and why bother...?
This is purely a personal preference. Maybe I'm a purist - though donning a short stonebashed denim kilt is hardly an indication of that! There is a satisfaction to be had in altering something to suit your preferences, especially if it works reasonably well as a result. I'm quite pleased with it for an item just under the four quid invested. 'Resourcefulness' is my middle name. Actually it's Robert...ooops, shouldn't have said that. The identity thieves will be closing in even more now

But they'll have to wear a kilt to get away with it.
