The Winner looks like line dancing to me although I thought that was done by cowboys. My cousin had the boots!
Never heard of the slosh, that looks like the Watusi to me.
I was a rocker so the only dance I did was the jive.
I've never heard of the Wigan Slosh and Google doesn't have many references to it either. Someone on this Twitter thread suggests that this dance looks similar though:

I remember the Slosh. I remember my parents doing that at the local hotel on NY Eve (1970s) while my friends and I were working our way through our parents booze collection. Happy days.
Pasta, did all those dance phases originate in the USA?
The only one of those I did was The twist, hitchhiker, and the swim.
The only one I can still do is the hand jive!
Clearly I didn't take much interest in jerking one's bod around looking like one was having some kind of episode, since I recall few of the above. But there again, one only partook in these femine type interests in order to meet girls. Otherwise one wouldn't have touched dances with a bargepole.
