For those of a certain pedigree (ie. longish in the dental department), Whitesnake at Hammersmith Odeon was iconic, a gig fans looked forward to with huge anticipation. For the band themselves, it came to represent something special, the benchmark against which their all other live dates were measured. And for all their subsequent success in arenas and stadia, nothing has ever compared to the Hammersmith Choir, as David Coverdale dubbed the audience at the venue.
