the first one is Disarm by the smashing pumpkins i think.
the second one is a track from 1984 i think, I think it was george michaels group or something. its called wake me up before you go-go, i think thats the one your looking for.
anyway, that track is called WHAM! - wake me up before you go-go
"Disarm" is a cool song. And yes, it's by Smashing Pumpkins. You know the basic chords? Just G and E (or is it Em?) Play G then "walk down" to E. That's the way I play it anyway. Get someone to ring a bell as you change chords. The only lyrics I can remember besides the one you posted is "I used to be a little boy. What's a boy supposed to do?"
"It's all right son . . . we told you what to dream"
