I was just watching a season 3 episode of The Fall Guy called 'Pirates of Nashville'. The main storyline was about bootlegged Country records, so Colt and gang had to fly to Nashville and visit The Grand Ole Opry. The first singer they met was Dottie West - one of Boss' Celebrity Speed Trap victims. A couple of others like Mickey Gilley were mentioned, but not seen. Then Charlie Daniels and his band showed up to perform 'The Devil Went Down to Georgia'. The episode also featured Miriam Byrd-Nethery who appeared in two episodes of Dukes. The episode finished with Colt losing a bet and having to sing the show's theme song which was portrayed as having been written by Howie.
I'm no expert on Tennessee geography, but the street signs in the urban car chase looked suspiciously like the ones in LA, and the out-of-town chase went down roads lined with white fencing that were very like the ones often seen in Dukes (e.g. W Potrero Road in Westlake Village).
