> Do we think it is a "real" song. It could well have been written to suit the story line.

I've not done any research but I got the feeling it was a portmanteau creation, picking 'n' mixing from a few songs to create a version which did fit the drama. Which I haven't got a problem with at all, but the series has now strayed so far from the source text that the authenticity of the music is the least of the issues if you want to start nit-picking.

I just wish the actor who plays Alf would learn to mime moving the melodeon in something like a realistic manner - very distracting!
