These songs are for John Updike fans. It’s one of the last songs Harry “Rabbit” Angstrom hears on the radio driving from his old home in Brewer, Pennsylvania, to the condo in Florida, where he and Janice have retired — only Janice is not with him, not on this drive almost at the very end of Rabbit at Rest, the fourth Rabbit book, set in the twilight of his life. Ray Charles sings I Can’t Stop Lovin’ You. Wow! A voice that cuts to your soul.
