I just got invited to be in an LGBT+ (and allies) marching band for the Pride parade in Limerick, Ireland in July. It'll be the first time that's been done in this country afaik. I know the folks organising it (and evidently they know about me) so it would be the real deal not some hodge podge of randomers with bugles.
I'd love to do it!! And definitely dressed, of course. But I have flights & accommodation already booked for the "Sparkle" event in Manchester UK that weekend. I am seriously thinking about cancelling...
