Lou Gramm is sharing some details about his role in the Foreigner 40th-Anniversary tour this summer. In a Tuesday interview on 'Trunk Nation,' the singer confirmed that he and the other founding members of the band will join the group's current lineup at several gigs. When asked for dates or locations, Gramm was vague, saying, "I think it's basically supposed to happen a few shows in the summer and a few in the fall. I think we're talking about maybe six shows, seven shows total. So that's about all I can say now. I'd love to tell you the names of the cities and stuff, but I was asked not to get too specific."
