silent comedy movie about a wake -1970's

I am trying to find a movie i saw in the 1970's. it was a 17 minute virtually silent movie regarding a wake were a drunk fell on a bed and knocked off the corpse. the drunk was put in the coffin and the funeral progressed. A person at the wake discovered the error and the chase after the funeral begins. the movie is halarious and I thought was called :its the only way to go:. it screened at drivein theatres across South Australia, would like to confirm name of movie and if possible where I can get a copy
