Edit: Be sure to check out the second installment of the myTouch commercials.

T-Mobile has a new TV commercial for their new Google Android phone, the myTouch.  I know nothing about the phone, but the commerical features Phil Jackson, Whoopi Goldberg and some tattooed guy who is likely someone that I should have heard of.  That catchy background music is the song If you Want to Sing Out by Cat Stevens. Check out the T-Mobile myTouch commercial:

And the full Cat Stevens song:

If you Want to Sing Out, Sing Out Lyrics

Well, if you want to sing out, sing out
And if you want to be free, be free
'Cause there's a million things to be
You know that there are

And if you want to live high, live high
And if you want to live low, live low
'Cause there's a million ways to go
You know that there are

[Chorus:]
You can do what you want
The opportunity's on
And if you can find a new way
You can do it today
You can make it all true
And you can make it undo
you see ah ah ah
its easy ah ah ah
You only need to know

Well if you want to say yes, say yes
And if you want to say no, say no
'Cause there's a million ways to go
You know that there are

And if you want to be me, be me
And if you want to be you, be you
'Cause there's a million things to do
You know that there are

[Chorus]

Well, if you want to sing out, sing out
And if you want to be free, be free
'Cause there's a million things to be
You know that there are
You know that there are
You know that there are
You know that there are
You know that there are 

EDIT: Turns out that third guy is someone named Jesse James.  Never heard of him.
