After more than 20 years, the 3 surviving members of the well known and extremely popular rock band, Led Zeppelin have come together on the stage for charity purposes. Robert Plant’s voice is just as gritty and harsh as it always was, despite him now being in his 60′s and it would appear that the band itself is just as popular as it was back in the 70′s. More than a million faithful fans queued for hours in order to be there to watch these aging rockers sing Stairway to Heaven and A Whole Lot of Love with just as much verve and aplomb as when they were young, invincible and invulnerable.
