No, the best way to handle it is this; whenever they start singing their "praise" song, sing along. When they come to the name "Jesus", loudly sing "Moloch" and when you sing it, it would help to maybe slobber and jerk a bit. Then when the song is over, start a "Moloch" cheer..."Gimme an 'M'...gimme an..." (Of course, have the rest of the gathering prepared beforehand to enthusiastically join in!) Do the cheer intermittently throughout the rest of the evening.

This should solve the problem.
