Sounds like Reuben and Cerise?
Wow. I guess I didn't miss it, since it didn't get played, and I'm not sure I've ever heard it on the radio. Some of Hunter's most intense lines:
The crowd pressed round
Ruby stood as though alone
Reuben's song took on a different tone
and he played it just for her
The song he played was the Carnival Parade
Each note cut a thread of Cerise's fate
It cut through like a blade
Reuben was playing the painted mandolin
When Ruby froze and turned to stone
for the strings played all alone
