I use "I Want To Go To Hollywood" a lot... it's good for young alto's... since most really great material that shows off the low notes are... geared more toward the older generation. Generally...
Here are some ones I've used...
"Hold On" ~Secret Garden
"Lost and Found" ~City of Angels
"Naughty Baby" ~Crazy For You/Primrose
"Arthur Murray Taught Me Dancing In a Hurry" (Johnny Mercer)
"The Miller's Son" ~A Little Night Music
"Sooner or Later" ~Dick Tracy
Um, if I think of more I'll post 'em. (As one who's got low notes for days, I's gots a lot up my sleeve... unfortunately my book is in the back seat of my car and there's a blizzard going on...)
"You! You are the worst thing to happen to musical theatre since Andrew Lloyd Webber! And you, well, I just plain don't like you."
