The point about Slades song is that its s a good song.

Look at the lyrics, it's someone describing a modern household celebrating Christmas. it has a catchy chorus and loads of people can relate to the lyrics.

I'm no fan of Slade, but I can see why its more valued by more people than stuff about wassailing.

wass'at? any way. If I caught anybody wassailing in our house, I'd give em a clip round the ear.
