Okay - I guess when I think of "big" voices, I think of Marin Mazzie and Judy Kaye..legitimate, classically trained, perfectly placed, with seamless registers, and powerfully produced without strain. But the comparison is pointless.... To each his own idea of "big" I guess!
P.S. The voice darkens with age, too, so Bernadette's "Dames at Sea" and "Gypsy" would be different. Im not sure how much more powerful it would get without pushing it beyond its limits, resulting in vocal problems, damage, etc. etc. Gotta give her credit though for a long career.
Just to let you know he was never asked to leave Rent or anything like that at all. Just wanted to clear that up don't want anyone starting something that is untrue.
