Band leader Mick Jones paired the current lineup of the band with its classic lineup for a number of special shows this past summer and fall.
In a new interview with Rock Band Reviews, Gramm says everyone got along and "we're gonna do some more, I think."
Gramm, multi-instrumentalist Ian McDonald and keyboardist Al Greenwood joined Jones and company onstage for the encore of a July show at Jones Beach Theater in New York.
Then in October the original lineup performed two shows in Michigan that were filmed for a coming release.
"It was great to get back onstage with the original Foreigner," Gramm said. "We played about six or seven songs; it was a lot of fun. And Mick, of course, played with us. And then the two bands — the Foreigner of today and the original Foreigner — actually played a few songs together, and that was also fun. And they are really nice guys and good musicians."
The singer added that "everything is kind of poised for a fun an interesting summer."
