After initially contesting reports that he had been invited to reunite with Foreigner on their upcoming 40th anniversary tour, singer Lou Gramm says he and his fellow surviving founding bandmates will indeed rejoin the group's current lineup "for a song or two" at an as-yet undetermined show.

"After 24 hours of some crossed wires and miscommunication, I can confirm that I and the rest of the original band have been invited to join Foreigner for a song or two at any show during this 40th anniversary year," Gramm explained on Twitter. "[Drummer] Dennis Elliot and [bassist] Rick Wills will be in St. Augustine, FL on 2/24. [multi-instrumentalist] Ian McDonald, [keyboardist] Al Greenwood and I will perform on a date yet to be determined."

Apart from a two-year break that started in 1990, Gramm served as Foreigner's lead singer from their formation in 1976 until 2003. Kelly Hansen has fronted the group since 2005. Guitarist Mick Jones - who together with Gramm was inducted into the Songwriters Hall of Fame in 2013 - is the sole remaining founding member in the band's current lineup.

Foreigner's 40th anniversary tour – featuring support from Cheap Trick and Jason Bonham - kicks off July 11th in Syracuse, N.Y., and is currently scheduled to wind up Sept. 9 in Auburn, Wash. A two-disc, 40-track compilation featuring some new material is also set for release this year, along with Jones' memoir, A Foreigner’s Tale.
