So once the the bass clef begins for the left hand, 2nd to last measure, you have to play insanely long chords. My hands can't even reach Gb to Bb fully stretched out...and I don't see how anyone can unless you have some huge hands.

If you haven't heard how he plays it:

So is the only thing I can do is omit a note? It almost sounds like he's playing it arpeggioted but I don't know.
