Does anyone know!!!

Hey everyone I just signed up to this website what a great idea. I just need help finding a song. It's from the 60's more likely 70's. I'm not sure if this is the title I just need the band name. It goes something like this, how can people be so ugly, how can I be hung up on you I think. Any help would be greatly appreciated.

I think you want the song "Easy to Be Hard." It's from the musical "Hair," but the big hit single was by Three Dog Night.

How can people be so heartless
How can people be so cruel
Easy to be hard
Easy to be cold

How can people have no feelings
How can they ignore their friends
Easy to be proud
Easy to say no

And especially people
Who care about strangers
Who care about evil
And social injustice
Do you only
Care about the bleeding crowd?
How about a needing friend?
I need a friend

How can people be so heartless
You know I'm hung up on you
Easy to give in
Easy to help out

And especially people
Who care about strangers
Who say they care about social injustice
Do you only
Care about the bleeding crowd
How about a needing friend?
I need a friend

How can people have no feelings
How can they ignore their friends
Easy to be hard
Easy to be cold
Easy to be proud
Easy to say no

Ah ha that's it thank you so much that is such a beautiful song.
