A Gathering

While at lifeboat training a small group started to gather, but why?
Were they waiting for a table at Cafe Fish?
Were they watching lifeboat training?
Well when they started singing we realised it was neither of these. Also, if we had seen the rather large cross just round the corner we might have realises sooner!
No it turns out they gather here just before easter each year to sing some hymns before walking all the way to Iona (over 50 miles away).
