Pam,
You look good, girl! Your hair is not big...lol.
You make me laugh, really, really, laugh and I just love your style.
You wanna sing the blues? Do you like the blues or is just the thought that your voice sounds better...I am confused about that part...lol.
Aren't there jazzy/bluesy songs that would suit you better than Muddy Waters?
Have you ever listened to any Nick Drake music? He's kind of inbetween Donovan and jazz...very hippy style blues maybe?
He's got stuff on YouTube if you care to hear him. Try 'Fly' 'Pink Moon' 'Cello Song' and see what you think.
You worry too much.
Don't change the hair....lol. You look great in that picture
