Jason, son of original Zep drummer John and his father's stand in at the band's reunion gig at the O2 Arena last year, said: "I've been working with Jimmy [Page] and John Paul [Jones] and trying to do some new material and some writing. I don't know what it will be, but it will be something.
"At the moment, all I know is I have the great pleasure to go and jam with the two guys and start work on some material. When I get there, I never ask any questions. If I get a phone call to go and play, I enjoy every moment of it. Whatever it ends up as, to get a chance to jam with two people like that, it is a phenomenal thing for me."
However, he said actually recording a new album could be a long way off: "Lots of politics [would need to] get ironed out [if an album was to be recorded, but] the possibility of doing something is in the cards. I really felt it was on the cards from the moment we walked offstage at the O2."
