That's why we have 2 services. One for the younger crowd and one for the traditional crowd.  Works quite well.  The 1st service has a band and has a more contemporary service while the second service has a choir and sings from the hymnal.  Some people go to the early service because they like to get done with church and have the day free even thought they are more traditional.  And of course the reverse is true for some that like to sleep late.

I don't care, as long as they are there for the fellowship and the worship.
