Lyrics Quiz: Eric's Two Themes

Eric presents a Lyrics Quiz with two separate (but equal) themes.

Theme A

1. So don't worry about tomorrow, take it today. Forget about the check, we'll get hell to pay.
   
2. Yeah, my whole family done give up on me, and it makes me feel oh so bad. The only one who'll hang out with me, is my dear Old Granddad.
   
3. Take another shot of courage, wonder why the right words never come, you just get numb.
   

Theme B

1. Climb in the back with your head in the clouds, and you're gone.
   
2. Every day I work so hard, bringing home my hard earned pay. Try to love you baby, but you push me away.
   
3. Don't forget this fact, you can't get it back.
   
4. When I first met you, didn't realize. I can't forget you, for your surprise.
   You introduced me, to my mind. And left me wanting, you and your kind.
   
5. Relax, relax, relax, I need some information first. Just the basic facts, can you show me where it hurts?
   

I only got the last one. (D'oh! Should have got B3 too!)
