The upcoming "Face 2 Face" tour starring Elton John [ tickets ] and Billy Joel [ tickets ] has expanded into August.

Since last check, July shows have been added at Columbus, OH's Nationwide Arena, Chicago's Wrigley Field, and Philadelphia's Citizen's Bank Park, where a 20-minute sellout prompted a second performance. Philly is the city that launched John and Joel's first-ever matchup in 1994, according to the Courier-Post newspaper.

The "Face 2 Face" outing, which now spans 27 dates in the US and Canada, is set to launch March 2 in Jacksonville, FL. Two-night stands are also booked in Toronto and Anaheim, CA. An updated itinerary is included below.

More shows are expected to roll in periodically, as the trek is planned to run off and on over the next two years.

John and Joel will literally come "Face 2 Face" during their concerts, starting each evening by playing a series of duets with twin pianos and trading vocals. The stars will then perform separately before joining once more for the grand finale, according to a press release. The shows are expected to include some of their greatest hits and a selection of rock-and-roll classics.

While the "Face 2 Face" tour takes a break in April, John will finish his Las Vegas "Red Piano" residency, which has been running since 2004. He'll also pop over to Europe for his own run of shows in June. Details can be found at the superstar's website.

John and Joel first toured together in 1994, and their most recent "Face 2 Face" outing was a sold-out, 24-date trek in 2003. The Grammy winners are the most successful and longest-running concert pairing in pop history, according to a press release.
