If you're like me - a reasonable supposition if you've elected to read this blog - then this TV documentary probably didn't seem the most enticing of prospects. Another excuse for a musical countdown: cue overfamiliar info, annoying celeb soundbites and those frustrating, miniscule fragments of the songs themselves which make you wonder why you're wasting your time when you could be, I dunno, writing a play or something.
Still, always a bit of manufactured tension to be savoured after you've allowed yourself to get hooked and fall to wondering just what songs will feature higher up the list - though to extract maximum enjoyment it's generally wiser to record this kind of show, not watch it live: that way you've got a fighting chance of skipping to the good, or goodish, bits without being driven crazy in the meantime by the aforesaid celebs' unremarkable musings or, worse, the portentous tones of a certain ubiquitous, rent-an-authority commentator.
In the event, however, he didn't feature, and in fact this show proved to be something a great deal better than the norm, which is why I'm writing about it below, and recommending that you catch it on BBC iplayer here, where it will be available to view in the UK until the 1st of February 2016.
