Looks like the band received an e-mail from the show's staff.

"Journey Song On Wheel of Fortune!!
Congratulations!
On behalf of "Wheel of Fortune", we would like to take a moment and let you know that the song "SPOILERXXXSPOILER" by Journey will be featured as a puzzle on the February 19, 2007 episode of our show.
"Wheel of Fortune", which has ranked as television's #1 syndicated series for 89 consecutive sweeps ratings periods, marked the beginning of it's 24th season on September 11, 2006. With over 19 million viewers daily, syndication's longest-running, most successful series continues to attract a larger audience than most primetime TV shows. "Wheel of Fortune" airs in 211 markets representing more than 99% of the United States.
The above was received in an email from the Wheel of Fortune staff and the title is not given so that all Journey fans and watchers can guess along with the rest of the nation."
If anyone here remembers to watch this on the 19th,I'd be curious to know which song did they pick.
