Take it easy old man. Don't hurt yourself! LOL Loverboy was a good concert for me. Never have seen Foreigner but they have a long list of great tunes. It should be a great concert for you two.
We saw Loverboy last summer and a guy sitting next to us was a manager and took us back to talk to Paul Dean their lead singer and guitarist. We talked to him for 10-15 minutes great guy.
