"So long" - with Wersimatic II

I got this Wersimatic drum machine/auto-orchestra unit working a couple of videos ago. But now somebody complained that I didn't show it actually working. Therefore in this video I play ABBA's "So long" on the Wersimatic II and Wersi Prisma organ. It is probably not what could be described as an action-packed video. Doing one-finger chords on a keyboard is not really mind-blowing in any way. But I hope that is proof enough that it works!
