I just found out that Randy recorded two songs for a movie called Faith in 1990. The songs are called 'You' and 'Into the Night'.
'Into the Night' can be heard here:

I'm having trouble finding 'You' but I haven't given up yet!
ETA: Gotta correct myself. The movie is American and not German like I originally posted. The clip is from the German dub of the movie.
