Great Gig in the Sky

Thanks to Google assistant for helping me figure this one out. Alexa, which advertises itself as doing this was useless.

Written by Rick Wright

Performed by Pink Floyd

And I am not frightened of dying
Any time will do, I don't mind
Why should I be frightened of dying?
There's no reason for it, you've gotta go sometime

If you can hear this whispering you are dying
