What did Dave Walker sing in concert?

So here is a question that has been puzzling me for a while. We know that Dave was only in the band for such a short time, but obviously he did live concerts with FM. So other than perhaps singing The Derelict and (I'm A) Roadrunner, what else did he do?

Did he sing other songs in concert? Did he just run around the stage bashing a tambourine and singing backing vocals (reminds me of someone else)?

At that time he was one of three main vocalists in the band so it would be fair to assume he would have taken up more of the lead vocal duties than two songs?

Anyone know?
