Why do people sing better in the bathroom???

Or don't they sing better in the bathroom? Well they kinda say in the shower but that wouldn't have worked too well with Greg's hot tub... anyways, here are some vocal tips let me know if it was helpful.
I personally got most out of the psychological stuff that we talked about.
And one more thing: If it looks as if I can hardly keep my eyes open then that's exactly true ;-) we shot this spontaniously after a long music night at Greg's awesome Villa... it must have been like 3:30am or something.
Thank you everybody who helped make that happen. And thank you dear life for sending the experience my way. I love you!
