C-Sharp gets religion?

There were signs around old Bisbee about a revival meeting that was going to be held in the Convention Center at 4 that afternoon. At about 3:30 I saw a woman carrying a batch of store-boughten chocolate chip cookies into the Convention Center.

I walked up Tombstone Canyon Blvd for a ways, and I saw C-Sharp, a local street musician. I listened to one of his songs, and tipped him a dollar. Then C-Sharp collected his tips, and packed up his guitar. He told me that there was a show happening at 4. Anyway the sun was setting.

Then as he packed up his guitar, he said that he wouldn't be there except for the sun. Or did he mean Son?
