I think that is it, although I swore the one I heard was a bit slower. Which is what I found odd because I'm sure I've heard every track available lol
While it's not acoustic, the ECB did a set of "AOL" sessions that were a little lighter than the typical live and studio versions of the song. You can find that version of smoke right here. Hopefully that's the one you're looking for as I'm not yet familiar with an actual acoustic version of the song.
