I went to their concert last Saturday. I had an awesome time to say the least. I hope I'm that energetic and passionate about something as much as they seem to be at 50 +.
They are still lovin' what they do in there mid 50's, which isn't old

,but to be rockin and rolling since they were teenagers and still going.. That's some longevity. Gotta love what your doing to keep at it that long.
Hope you get a chance to see them. You won't be disappointed.
