Best way to watch The Wrong Trousers in high quality with the original soundtrack?

Hey everyone! Thanks for helping me out so far with here, hopefully I get to chat and learn more from you smart inventors here! I was wondering if theres a way to watch the wrong trousers in a high quality version (like how the amazon prime or Blu-ray releases have it) but with the original soundtrack with the happy bday theme and original organ music as seen when Gromit cannot sleep. Help would be appreciated to find an official or fanmade edit to watch it as it was intended, thanks! (Don’t mind the almighty Gromit mug, he chill)
