WHAT do you think of when you hear a song by The Who?

Do you focus on the powerful drumming of Keith Moon, Roger Daltrey's vocals, the showmanship of guitar hero Pete Townshend or the complex basslines of John Entwistle?

Or do you think of guitars being smashed, drum kits exploding or expensive cars ending up in swimming pools?

News Shopper: The Who

The Biography Channel's DVD charts the story of one of the greatest rock bands of all time, from the band's early years to the recent studio album Endless Wire via Tommy, Who's Next and Quadrophenia.

It certainly has a nice mix of talking heads, including John Entwistle's first wife, Keith Moon's former assistant and a range of authors who have written Who-related books.

And this documentary also includes some good footage of the band's early days, when Townshend was still perfecting his windmill guitar-playing style but already knew how best to destroy his instrument.

So far, so good. But this DVD does have some serious drawbacks.

The first is the 45-minute length (no doubt it would fill an hour on TV with advert breaks) which makes it very difficult to tell the story of a long-running band in great depth.

A band this big and this good could and should warrant a longer documentary - at least double the length.

Another problem is the shortage of footage used.

Aside from the clips mentioned earlier, there is not a whole lot more footage of the band in action.

There are no clips from the video of Won't Get Fooled Again, so we are denied the chance to see Townsend slide across the stage on his knees in full rock God mode, or see Moon's incredible drum solo.

The tale of Moon's exploding drum kit on the Smothers Brothers TV show is mentioned and a photo is used, but we don't get to see it happen.

And there are also no clips from the Tommy and Quadrophenia films.

Add an over-reliance on the same few photos of the band and no DVD extras and it feels a bit incomplete.

To really get an idea of how explosive The Who were, you would be better off buying The Kids Are Alright, as then you get to see the memorable TV clips as well as the band's most memorable performances.
