No apologies for the attempted semi-hijack - I thought it was more interesting than the main topic of this discussion.

I saw the Albion Dance Band play a ceilidh at Trinity School Croydon, at Christmas...

1974?
Fits best with my other (vague) recollections, but seems a bit early for the ADB
1975?
1976?
Seems a bit late (I hadn't caught on to punk by Christmas 1976, but I'm fairly sure I'd stopped wearing the shirt I remember wearing* that night)

Christmas 1975 seems most likely, but I'd prefer it to have been 1974. Any thoughts?

*It was a memorable shirt. It was printed with a 'Dougal'** motif and had flared sleeves. I wore it a lot. Sometimes close friends pretended they weren't with me.
