You know your too old to gig when
A search party has to go and find you.
You forget why you are there.
Someone has to help you onto the stage.
Your Zimmer gets caught up in the cables.
An old flame you cannot remember, introduces you to your unknown Son who has Grandchildren.
Your clothes are so old they are back in fashion.
When your Nurse is in the audience.
