Led Zeppelin guitarist Jimmy Page has said that led Zeppelin may play a previously unheard song at their forthcoming one-off reunion concert.

Page revealed that the bad have been rehearsing a song which dates from between 1968 and 1980.

"There's one number that we rehearsed, I assume that it will make it to the Dome, that we never played at any point in time,” he told Reuters.

Page, who is currently recovering from a broken finger which forced the postponement of the concert, described the song as “a really intense number."

The band will play at the O2 Arena in London on December 10th. Page has also revealed that the band will reconvene for rehearsals later this week.
