Luckily, West End audiences seem to rather like very old people.

Don't hustle old people.

Old deeds for old people, and new deeds for new.

People become stingy as they grow old.

Some old people, they remember that they used to play clarinet, and they remember the squeaks of the clarinet. But I don't play like that.

You know you must be doing something right if old people like you.
