Film and song title has escaped me

Hey all,
Had this song stuck in my head all morning and I can’t for the life of me find it! All I remember is the refrain, “Friend for a day”, which would usually be all I need to find it or the film it’s from, but I can’t find a single thing! I’m pretty sure it’s one of those Bud Spencer-Terence Hill comedies or something like it.

Perhaps you remember it wrong and it’s “A King for a Day” sung by Augusto Martelli, in which case the movie would be Sartana in the Valley of Death.
