Film teenager goes searching for something left by dad

Hi,

I’m looking for the title of a movie, but I can only remember bits and pieces about the story.  The main character was a teenage boy whose dad has died and goes looking for something that he left.

There is one scene where he is searching for a key in a diner.  It has something to do with when his parents first met.  The diner catches fire but he remembers at the last minute that his dad used to hide things taped under the table and finds the key under the jukebox.

There is also a scene towards the end where he and a girl are in a car that is being towed away and they climb through the window onto the tow truck while it is moving.

I saw this film in the early 2000s but the movie was definitely made before then, probably 80s or 90s.  It featured the song “Blue Eyes Crying in the Rain”, I think sung by Willie Nelson, so it has to have been made before 1975.  It was on VHS and I had checked it out at the church library so the rating should be probably G or PG.

Thanks

Got something to say?
