I have all of these except the Cross Road one...a lot of the crowd noise between the tracks have been faded into each other so they sound like a continuous live show, so some of the running times will be different from the B-side versions because of this.

To answer your questions:

Roulette (BBC Friday Rock Show) - From the In and out Of Love single - 5:36
Get Ready (Japan 85) - From the Wanted silver vinyl single - 7:04
Breakout (Super Rock 84) - From the Runaway single - 6:12

Bad Medicine, there are two versions on the disc - one from the Lay Your Hand On Me single (Wembley 88 - 5:53) and one from the I'll Sleep When i'm Dead CD single (New Jersey, Keep The Faith tour - 8:22)
