Phil (not-Flood) has previously posted this song and it included the gnarrr feedback at the beginning of the song. (I think it required a special adaptation of the NP Vintage Ludwig Bass kit to include the wav for the feedback sound).
What’s been updated on my post? New source file, additional version (DOP), different kit used, lowered the velocities of the bass and cymbals to attenuate the volume and refined the cheat sheet. This post does not include the guitar feedback during the intro and if you want Phil’s excellent version, it’s in a BeatBuddy Manager (BBM) folder here Many of my previous posts .... BEATLES 2017-12-16 - BEATLES FOLDER but you’ll probably have to message him for the modified kit.
