My interpretation would be... Live vid, a straight recording of the band playing thru a song..
.. A video shoot would be a film version with lots of shots and angles cut in and edited etc, along to a backing track, not a live recording..
I used to walk around barefoot quite a lot, and even drove a motor likewise but I'd definitely not be playing a gig or rehearsal room without footwear.
I suppose you could take your own nice bit of carpet with you and roll it out to stand on, might be an interesting stage gimmick...
I think the Tokai stuff in the 80s was japanese, I'd think anything after would be Korea then China.
Great looking bass, I've never had a thunderbird type but quite fancy trying one...
