Well, I suppose it was inevitable. Someone had to start this genre. This is what I heard happened.

Helen arrived in Heaven and Saint Peter welcomed her at the pearly gates. Saint Peter walked with her over to see God who was leading the Heavenly Choir. Arranged on the slopes of four nearby hills there were 100,000 sopranos, 100,000 altos, 100,000 tenors and 100,000 basses.

God greeted Helen warmly and told her that they had all been waiting for her. Then He asked her to sing as soloist in "Palms of Victory." Helen accepted graciously and walked over to her place on top of a fifth hill.

God waved his baton and Helen sang the first verse. It was just as beautiful as it used to be on Earth. Then everyone began to sing the chorus. But God quickly stopped the singing by tapping His baton on His podium and holding up his hand. "A little less volume from the soloist, please." He said. And then they began again.

P.S., My source assures me that this is what really happened, and it is just a coincidence that it sounds vaguely like an old Welsh tale.
