... what are they doing to preserve their voice for the night? How, how, how are they using that technique to make sure that when the big im- big performance comes, they're ready?

So I think it's a lot to do with vocal rest actually.

The professional singers will not be going to the pubs.

They will not be drinking.

They will be, um, using a humidifier for their voices then between all of these interviews.

They'll be doing their vocal warmups.

They'll be doing their vocal cool downs.

I mean, we're talking about the voice as being as technically advanced and as looked after and as nurtured as those pieces of equipment and those staging concepts.
