Not "slow and painful" - think of it as "slow and sorrowfully". The preamble to my ancient copy takes pains to impress that it's dance music so it has to at least kinda lope along a bit rather than a death march.
You can play #1 pretty fast and it sounds great imo (maybe since the tune is so familiar). 2 & 3 don't work as well.
