Does anyone know what song was played in the build up before the players walked out the tunnel?

It was the one that started with bells donging and was a heavy rock/metal track, played before the Led Zepplin mix.

Along with the horns being back (Fanfare for the common man - Emerson, Lake & Palmer) leading into Hi Ho Silver Lining, the music finally felt on point and built the walkout perfectly.
