I saw Aerosmith twice, in 1989 and 1993.
I have had a memory of the second show, when somebody called out for them to play Rats In The Cellar - one of my favourite 'Smith tunes - and Stephen Tyler saying 'Good choice' and them playing it.
I'm currently listening to a naughty recording of the show which was posted on the site where these things are posted, and my memory is there for me to hear once again several decades later.
Nice to know my grey matter is still working.
