As first tipped here last month, Creed is hammering out details for a lucrative 2009 reunion tour, sources tell Billboard. The Scott Stapp-led group, which was one of the top sellers of the past decade, has not performed since a rancorous split in June 2004.

Stapp promptly embarked on a solo career, while guitarist Mark Tremonti, drummer Scott Phillips and original bassist Brian Marshall formed Alter Bridge with vocalist Myles Kennedy and released two albums. The 2004 Wind-Up debut, "One Day Remains," sold 496,000 copies in the United States, according to Nielsen SoundScan; a 2006 follow-up for Universal, "Blackbird," has moved 227,000.

However, Kennedy is rumored to be the top contender to replace Robert Plant for a tour with Led Zeppelin's Jimmy Page and John Paul Jones. And following a recent USO tour performing for American servicemen oversees, Stapp is said to be in prime physical and mental condition.

As such, there are "significant dollars" on the table for a Creed trek, according to sources close to the situation, who say an official announcement could be imminent. A spokesperson for Wind-Up tells Billboard, "There have been some talks, but it would be premature to comment on them at this time."

Creed has sold 26.1 million albums in the United States since 1997, according to Nielsen SoundScan. The group was also a significant touring presence, having grossed more than $70.3 million from 220 shows reported to Billboard Boxscore between Nov. 1997 and Dec. 2002.
