Don’t buy a used car from Dan Beckmann, or at least from his current persona of Jonas Candide in “The Fields of Ambrosia.”

The show, running at Surflight Theatre through Sept. 25, is an interesting, quirky musical with some soaring songs by composer Martin Silvestri, heaping helpings of black comedy, a prison rape, and enough deaths to keep an undertaker working overtime.

Most of all, “The Fields of Ambrosia” is a star vehicle.

Its book and lyrics were written by Joel Higgins, who was a busy man in the 1970s and 1980s.
