I've found nursing home audiences to be very enthusiastic. They don't seem to be fussy about anything - songs that mention death and old age are fine with them. They do seem to prefer songs that they know, songs that spark a memory.
In the first message, Genie listed

Try To Remember
Don't Fence Me In
Dry Bones
I Almost Lost My Mind
Urge For Goin'

I think nursing home audiences would like the first three, but they wouldn't know the last two and wouldn't relate to them. Familiarity is the key - they don't mind being reminded of being old or or facing death.
