If I had a penny for every time that someone has asked where they could find these videos, I'd have enough money for a full day session at the pub!
Seriously, these videos are amongst the Seal's "Most Wanted" items, even though the tapes are easily available.
"Why?", you may ask. Unfortunately the VHS cassettes are widely available in PAL video format, which is total useless to home video equiped US/Candian/Japanese folks who are stuck with the awful NTSC format.
The laserdiscs are a different matter. They're quite impossible to get hold of!
