Guy should have been allowed to live the rest of his life in dignity quietly, tending to his garden, not tap dancing for 40+ year old adults still obsessed with "The Time Warp".
Even if he did... he was in bad shape and it must have been physically taxing.
The thought of him feeling obligated to be on stage in front of a room of wide-eyed adult children is particularly sad. This is more a commentary on his fans than Tim himself.
Others here are saying, like Ozzy, he might have been doing what he wanted to do.
To quote the poet, Dylan Thomas,
Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light.

You dont become Tim Curry unless you live for the attention. I highly doubt it was against his will. Shatner is still out there doing the theater circuit right now at nearly 100. Those generations in general (Silents and GIs) just had the mindset of "I'll stop working when I'm dead". It was the later Boomers really that latched onto the concept of retirement.
