Judging by the way their joints were cracking as they danced I wanted to say ’Great grandmother and great great grandmother?’ but I’m a yellow belly and instead ventured in with ’Sisters?’. They seemed quite happy with that.

They pulled off a Celtic fashion headwear coup by combining a leprechaun buckle hat AND shamrock deelyboppers. As they jigged the pair shook  empty Guinness tins to collect from passers by. I think theywere  grey haired, green faced buskers, but I’m not sure because they stepdanced sideways away from me when I asked if they were collecting for a charity.

I gave them £2 for baffling me so completely.
