Booked a friend for a Concert

I just booked a friend of mine, Marty Haggard, for a concert at my church next Feb. for our 5th anniversary of our church.  I also called a pastor friend of mine and they booked him too.  I met Marty a while back and I played the piano for the offeratory.  Marty smiled at me and as I walked past him he asked "did you ever play in taverns and bars"?  I said "yes , for many years".  I am excited about him coming to the church I pastor.  Marty is the son of Merle Haggard.
