Holy cow, Madeline has a fantastic voice. It is so strong, especially for an 8 year old. It will only get stronger and better as she gets older. I am simply blown away!

I envy them because they're so good

i have watched this so many times in a row. it never gets annoying or old. i cant stop listening to it!

Wow that was spot on. Wish I could hear them live.

okay i could replay this video about a million times. this is probably one of the most amazing things i've ever heard. oh my goodness, and madeline is only 8 years old! these children are amazing talented, god obvious blessed them with a wonderful gift to show to the world. amazing, truely amazing.

Perfect pitch, perfect harmony. These youngsters are unbelievable, I hope they keep soaring to higher heights

It´s amazing how much talent they have. And they´re so young! Unbelieveble

madeline's voice just soars. her transitions between "legit" singing and belting are flawless! both of them are extremely talented and i can't stop listening! absolutely beautiful!

After many listens, I still can not believe this!! Just plain WOW!

8 years old... simply amazing.

Madeline amazes me every time I hear her.

They are so good! I can't stop listening to this!

Wow. Just wow. What voices. Fabulous ending. Everytime I listen to this I am just astounded.

amazing... absolutely amazing. One of my favorite songs and these two girls only prove why it is so amazing.

You can't but help feeling happy when you here this. I'm inspired to do something for the world, make my own difference. I think that's what they set out to do in the first place, so, to the Cactus Cuties, thanks and good job.

10 and 8, unbelievable!!!!!

Madeline's Voice is really sweet ! Andi's voice is really good too ! :)

This gave me goosebumbs. They sing better than I do. The last part really impressed me.

The DVD they just released has this performance... it is AWESOME, and you get 21 other awesome songs! AND videos of the first Cactus Theater appearances of each girl... Madeline was 4!

wow. BEST kid version...EVER.

Agreed -- I will keep a eye on these very talented young ladies. As they mature their voices get better. And the twang gives them character,

the ending... is completely outstanding! actually the WHOLE THING is completely outstanding!

SO SOOOOOOOOO GOOD

AMazing!! Madeline is amazing!!!

if only everyone else on youtube that posted themselves singing this song could be this amazing!

Amazingly strong voice both girls have. Wonderful to listen to. Best Wishes.

8 years old and a voice like that? omg i got shivers

YES, they have a DVD composed from two live concerts done last April... it is said to have a grand mix of solos duets, group songs and should satisfy everyone's 'wants'. The release will be announced on this and the Backstage Channel I am sure. Should be soon!

Wow - I never knew they did this song before the 09 concert. Those of you who love this, download the newer version (and the whole album!) from iTunes - it's even more awesome! My favourite song on the album & DVD!

I'm so choked up I can hardly speak, and I've seen (and love) the real thing! Can I ever direct you guys??!! Kudos to your voice teachers for keeping it correct--take care of those amazing God-given gifts! Use them well!

you guys sing a great version of this song! my favorite musical. you guyys are a great talent. keep singing guys.

To truly appreciate the talents these girls have this MUST be seen as they do on stage in their DVD, their acting brings a life to the song that just cannot be fathomed by listening alone. They are truly remarkable actresses in addition to their marvelous vocal capabilities!

I love this song its one of my favourites And these two sung it amazingly! So such young ages they have incredablly mature voices Imagine what they'll sing like in a few years

Wow. This is so amazing. At any age, it's awe-inspiring. At such a young age, it's truly phenomenal.

Goosebumps!!

Bullhead003 tells it like it is! Their acting during this number is tremendous, just brings the song to life as it should on stage, the girls are really quite excellent in all their animations, but this is truly exceptional. Just another great reason to get the DVD! :- )

these girls are amazing. especially for being 11 and 8 years old! i have heard 30 year olds who aren't as good as them! it blows me away! the ending is unbelievable!

OH MY GOD THEY ARE SO GOOD!
