What is mash theme song?

The theme song for the TV show MASH is called "Suicide is Painless". It was written by Johnny Mandel and the lyrics were written by Michael Altman. The song was originally written for the 1970 film MASH, and it was later used as the theme song for the popular TV series that aired from 1972 to 1983.
