Can't figure out if
森慎太郎 on this album is actually the comedian (in which case the reading would really be "Shintarou Mori"). Either way, the name is registered on JASRAC as "Mori Shintarou". I also found a page where he's listed as an "artist" (whatever that means in this case... artist as in musician?):
