iTunes Not Letting Me "Join" Tracks!!!

[PrometheusG5]

For some reason, iTunes has the "Join Tracks" option grayed out when I am importing from a particular CD. I am trying to join Pink Floyd's "Shine On You Crazy Diamond" pieces - one is track 1, the other is track 5. When I select them, the option is grayed out. Do the tracks need to be contiguous on the CD to join them?

Do the tracks need to be contiguous on the CD to join them?

Yes.

Another wish-list for iTunes 5...
