Correct me if I'm wrong

You're wrong.

Unless you can tell me which previous winners Lau; Tom McConville; Jim Moray; Demon Barbers and Chris Wood are "connected" to....

Jim Moray and Jackie Oates are brother and sister of course, so maybe there is a "connection" there.

It is possible to find a connection - they have all made records for example. Is that what you meant?
