Ono Puncho Theme is missing from the soundtrack on all releases

[Unsu]

Title.

I cannot find this theme anywhere. Any help would be appreciated or if it is considered royalty free to have direction to where to find this! It's a good song, unsure if there are any additional songs that aren't included in the soundtrack.

Love the game and the soundtrack, but definitely will not be buying the soundtrack yet without detailed information on where certain songs can be found or a disclaimer that they are not included! <3
