Love Machine by Occult Academy's Maya!

Roamed a around a little and stumbled upon xxxholic/wing's post about Maya Kumashiro of Occult Academy doing a cover of Morning Musume's 1999 hit, Love Machine... while seeing an edited music video with scenes coming from the anime which includes zombie headmaster dancing!

Fun fact: Maya's seiyuu, Yoko Hikasa is also the seiyuu of K-ON!'s Mio Akiyama. No wonder I was fangasming a little bit while hearing her sing! For the full length cover, you can check this one. For the original Morning Musume hit, you can check this one.
