Competition Winners

Here's two normal looking blokes. Know who they are? They're part of a huge band, a four piece - one that has sold millions of records - one that has an album in the charts RIGHT NOW - one that has appeared across UK media in the last two weeks - including Later With Jools, to promote that album, but! If they were replaced - would anyone notice or care? Have they done this deliberately so they can remain virtually invisible to the general public, or are they actually competition winners?
