Can't figure out easy 70's song

I've seen this numerous times on tv shows like that 70's show and on some commercials.

Part of it is like "you and me, we've got to be," somethin somethin.
and the chorus has "togetherrrrrr" in it "I just feel on top of the world and".. or something like taht

Can't tell what else they are saying but this should be an easy one for 70's music buffs

TIA!

The Turtles - Song: Happy Together
