i used this tab at first, www.songsterr.com/a/wsa/uchu-conbini-8films-tab-s397039t0 but i play it in DADGAD rather than open D because it's a bit more comfortable and there's a 12th fret harmonic in the original that i don't do in this cover that's the top 3 GAD strings. hope you learn it and have as much fun with it as i do!
