When Led Zeppelin performed at Live Aid in 1985, there was a lot of tension within the band and their performance on the day was lacklustre. The members seemingly blamed it on guest drummer Phil Collins.

In December 2007 the remaining members reunited at the london O2 arena as a tribute for Atlantic Records founder Ahmet Ertegun who had died a year earlier. Jason Bonham replaced his father on drums.

This is the concert documentary of the one off performance attended by celebrities and ordinary mortals who were lucky enough to get the few available tickets.

The band older, greyer still give a rocking performance of some of their greatest hits. They also chat to the audience. For a rock band there is an underlying current of rhythm and blues, English folk, even world music in some of their hit songs. I rather liked the subdued version of Stairways to Heaven which has acquired a rather cheesy reputation over the years.

I have to admit I was too young when the band was at their pomp in the 1970s. I guess them not releasing any singles did not help. Ironic as one of their best known song was used as the theme tune for Top of the Pops. So I do not regard myself as a fan and not all too familiar with their back catalogue. However if you want to know a bit more about their music and just see some plain rocking this would be a good introduction.

On 12 December 2007 legendary rock band Led Zeppelin reformed to perform a tribute concert for Atlantic Records founder Ahmed Ertegun. This is that concert. The concert, performed at London's O2 Arena, included their most well-known songs. Set list: Good Times, Bad Times; Ramble On; Black Dog; In My Time of Dying; For Your Life; Trampled Under Foot; Nobody's Fault But Mine; No Quarter; Since I've Been Loving You; Dazed and Confused; Stairway to Heaven; The Song Remains the Same; Misty Mountain Hop; Kashmir; Whole Lotta Love; Rock and Roll.

Great concert, and capture of it. Good choice of songs. Nothing major gets left out (OK, maybe Immigrant Song, but I could understand if Robert Plant didn't feel he could manage the vocals on that any more).

While Led Zep might not have the energy and swagger of the 70s, when they were the undisputed kings of concerts, and rock music generally, their musicianship and artistry is undiminished. The power is still there too.

If anything, the music sounds tighter and fuller than in the 70s. Some of this is due to advances in live recording techniques and technology. Some of it could be due to guitarist Jimmy Page now not being under the influence of drugs...

If you compare this to The Song Remains the Same, the film of Led Zep's 1974 Madison Square Garden concerts, I probably prefer the music in The Song Remains the Same (we won't go into the non-music side of TSRTS - some of that was incredibly cheesy and certainly diminished the quality of the film). There's a rawness about it, and there's the Led Zep mystique too. Celebration Day isn't too far behind though.

For anyone who hasn't heard of Led Zeppelin, these talented, British dudes (who reigned supreme throughout the psychedelic 70s) were, at the height of their careers, the undisputed Gods of Heavy Metal/Rock'n'Roll, bar none.

Back in those days of songwriting glory, Led Zeppelin's concerts broke world records for attendance and their albums sold-out by the millions.

Now, in 2007 (nearly 40 years after their inception),Led Zeppelin reunited at 02 Arena, London, to treat their ever-loyal fans (young & old) to a trip down memory lane as they delivered 16 of their best remembered tunes (including Stairway To Heaven) to an enthusiastically cheering crowd.

With the 3 remaining original members of Led Zeppelin now being 60+ years old, I honestly have to say that I found their performance on stage to be noticeably tired and lacking in any youthful vitality. Even though Plant, Page & Jones were obviously well-rehearsed for this concert (and Plant even got a new perm just for the occasion),I couldn't help but notice that (between all of the robotic, rock-star gestures and posturing) there was a decidedly bored look on all of their 3 faces.

This, in turn, made it quite difficult for me to watch these dudes with any real enjoyment while they (rather listlessly) strut around on stage like peacocks at only half mast.

Anyways - I'd say that this DVD titled "Celebration Day" was at least worth a view. But, personally speaking, I'm one who prefers to remember Led Zeppelin as they were in the days of their youth, rather than as I saw them now as stiff, old men trying (desperately?) to retain an image of who they were 30+ years ago, that has long ago faded away into the past.
