I once sang in a choir whose conductor was accident and error prone and when she sang solo would forget words.
The audiences loved her as she had the uncanny knack to turn everything into an enjoyable experience for the audience through her personality and stage craft.
I have learnt from her and now do not worry when things go wrong but use it to my advantage with humour and any thing at my disposal and have a good time.
Murphy's law always prevails.
