I would say the songs that have different lyrics. I always write the music first, and there's a couple of songs on this box set that have different lyrics from what ended up on the final recording.
It feels great to have a #1 album.
The graduations hang on the wall, but they never really helped us at all.
You can linger too long in your dreams.
If you said good-bye to me tonight, There would still be music left to write.
...And you're the only one who knows.
