I want to thank you guys. I've been thinking about this movie since I saw it on late night TV almost 40 years ago while baby-sitting my siblings. All I could remember was that there was a Scottish solder who was sick, and whose compatriots were always trying to find out what he wore (or didn't) under his kilt. Your description of the movie and its title rang memory bells for me! Now I've got a used copy on order. Thanks!
