Tamu is calling back to Journey's drummer who had a huge mustache and played with an underhand grip, which is the reason for the tape mustache and the grip on her sticks. The walk-byes by Mayu's husband are callbacks to the original video where the girl walks by. The air band sections is also a call out to the video, and Mayu's rolled up sleeves are too.
I couldn’t agree more. Happiness is infectious. Nemophila always has fun and spreads positivity. I enjoy all the, “Easter Eggs,” otherwise known as homages to the original videos in the vast majority of their covers.
Hands holding drumsticks. Synthesizer. Guitar tones. And, incidentally, the drum make-up. How much research did you do? It's interesting that you're a bit assertive.
