Bumping this up as I think something like 240 photos have been added, most recently...
Giselle (Benjamin & Stiefel, lots of Sarah Wildor)
Enduring Images (that rather controversial pic of Alina in Vertiginous is there by the way and she is indeed at an angle to the stage. Her legs aren't quite six o'clock but more like five to five )
Romeo & Juliet (BRB)
And lots more - Sarah & Bruce Samson and Collier & Eagling in Manon, Alina & Bruce in Symphonic Variations, Collier and Bujones in La Fille, Irek, Viv and Adam Cooper in Judas Tree, Galeazzi, Persson & Watson in Triad, Stravinsky Staged, Cinderella, William Trevitt as Siegfried, Darcey/Jonny, Sylvie/Jonny, Miyako & Carlos in Coppelia, the Kirov in R&J, Makarova with the Kirov in Giselle, Fonteyn, Nureyev, Baryshnikov...
