It's that little souvenir.

An Ulster Hall tea towel we brought back from Belfast a fortnight ago. 
I saw The Undertones play the Ulster Hall in 1980, in a gig most memorable for the policemen armed with sub-machine guns who lined the back of the hall just before the band came on. 
The Ulster Hall  should also have been the  venue for a famously cancelled Clash gig in 1977. 
And, I only found out two months ago, it's the venue where Led Zeppelin gave the first ever live performance of Stairway To Heaven back in 1971.
