My brother went to see Bob Dylan recently, and I guess he fits in to this category. His voice, while many might debate it was never any good, was terrible. However, he really enjoyed it just because of the experience of seeing such a great performer. But I must agree with you, Meat Loaf's performance was just shockingly terrible.
All that is gold does not glitter, Not all those who wander are lost; The old that is strong does not wither, Deep roots are not reached by the frost.
-J.R.R. Tolkien, "All That is Gold Does Not Glitter".
