It would be big. Potentially one of the biggest ever. I'm talking, of course, about the increased chatter regarding a LED ZEPPELIN reunion tour for 2008 featuring founding members Robert Plant on vocals, Jimmy Page on guitar and John Paul Jones on bass, with Jason Bonham, son of the late Zep drummer John Bonham, manning the skins.

There has been no announcement that this tour is going to happen, and Plant has publicly denied it will take place. Billboard in general and myself in particular aren't usually in the rumor business. But this thing is starting to take on a certain air of reality. Maybe it's just wishful thinking.

For years, a Led Zeppelin tour, or the closest thing to it in the absence of John Bonham, has been considered the holy grail of the touring world.

Plant and Page toured arenas together in the mid-'90s. With a killer backing band, the pair reported $31.4 million from 63 shows that drew 1,028,678 people. That was enough to make Plant/Page the seventh-grossing tour of the year at a time when the Rolling Stones, the Grateful Dead and the Eagles were all touring stadiums.

And remember, 1995 was the cusp of exploding ticket prices. A ticket price higher than $100 was rare; the Stones topped out most dates at $50 that year, the Dead were $33.50 tops and the Eagles had shattered the glass ceiling but were still mostly less than $100.

While the days of coast-to-coast stadium tours appear to be behind us, a Led Zeppelin tour will undoubtedly play scattered stadiums in North America and probably all stadiums in Europe. The tour would most likely be a creative "mix and match" route similar to what the Stones have done recently.

So let's be conservative and say Led Zeppelin averages $225 per ticket, with top seats at a Stones-esque $450 and a low end at $75. It's a big production, so you get an arena capacity of about 15,000 max. Say 5,000 tickets at $75, 5,000 at $200, 3,000 at $300 and 2,000 at $450, for the sake of discussion. That comes to a gross of $3.2 million for one night.

Suddenly those 1,028,678 headbangers Plant and Page played to in 1995 generate a gross of $231,452,550 in 2008. From those 63 shows the average gross is now $3.7 million, compared with slightly less than $500,000 per night then.
