OK, so it's early 1976 and a band you love a lot and have seen live many times has lost their charismatic (see what I did there!) front man for reasons no-one understands and you hear that the drummer is now the lead singer. You have misgivings. Nevertheless, you buy their new album on the day of its release, take it home and then you hear the opening track. And you can't quite believe just how good it is!
