Album: 10cc, Tenology (Universal)

Now that we have finally broken the connection between guilt and pleasure when it comes to music, it's time to reappraise these stalwarts of the 1970s pop charts.

And though the odd irritating single makes it on to this four-CD-one-DVD celebration of their 40th birthday, there are enough album tracks and B-sides to make the case that what we actually had in 10cc was a British Steely Dan: clever, funny and funky as hell when they wanted to be.
