Watch: Foreigner classic era members reunites to perform 'Long, Long Way from Home'

Foreigner fans hoping to see a reunion of the core line up recently got treated to the next best thing, and the footage was posted on July 21 via Foreigner's official YouTube channel. A long awaited reunion between Foreigner co-founder and guitarist Mick Jones with ex-Foreigner co-founders Lou Gramm (lead vocals), Al Greenwood  ((keyboards) and Ian McDonald (sax) has finally taken place.

Rolling Stone reports on July 21 that the four long estranged classic era members performed together for the first time in 37 years on July 20 in Wantagh, New York. The performance was at Jones Beach Theater and a part of Foreigner's ongoing 40th anniversary celebrations. After performing the initial set with the current Foreigner line up, Jones and company returned for an encore and thrilled the fans at Jones Beach Theater by welcoming his long estranged bandmates.

It was a huge moment and Jones was visibly choked with emotion as Gramm, Greenwood and McDonald joined him onstage. The reunited multi-platinum sellers rocked through three classic Foreigner singles, including: “Long, Long Way From Home,” “I Want to Know What Live Is” and “Hot Blooded.”

Fans can check out the footage of Jones' introduction and the first encore number – the third single from their 1977 self-titled debut “Long, Long Way From Home.” Gramm displays the vocal chops that made him one of rock's premiere frontmen as he sings, “It was a Monday/A day like any other day/I left a small town/For the apple in decay.”

"It was great to have Lou, Al and Ian join us onstage last night, Jones writes in his notes below his YouTube posting. “(It) certainly brought back some special memories."

The appearance by Gramm, Greenwood and McDonald was the second time during Foreigner's current 40th Anniversary Tour, that former members have joined Jones to perform. Ex-Foreigner drummer Dennis Elliot and former bassist Rick Wills sat in with the current line up on Feb. 24 in St. Augustine, Florida.

Gramm and Jones last appeared together at the pair's induction into the Songwriters Hall of Fame back in 2013. It remains uncertain whether any other reunion performances will take place during the current tour.

Foreigner embarked upon their current US summer tour in support of their latest greatest hits compilation Foreigner 40, which dropped May 19 via Rhino. The powerful triple bill, which features huge support from Cheap Trick and Jason Bonham's Led Zeppelin Experience, kicked off July 11 in Syracuse, New York, and will continue on July 25 in Bristow, Virigina, at Jiffy Lube Live.
