Query: The Doo-Wah Riders win the hearts of all who listen to them!

Not only am I a personal friend, but I'm a huge fan! Their music is awesome and the whole band is extreamly friendly! I remember helping them with a concert in the town square of Chicago, and EVERYONE was coming up to me asking me about the band and telling me how great they were! Keep up the great work, guys!
