World Turning - I know a lot of people don't like this one...but I think it's a fun song.
They elected to use the loose format (i.e. 18 minutes) and adapted it to Not That Funny, almost the same song.

The Ledge - I've heard one bootleg of this song I think from one of the Melbourne shows in 1980...it's a fun little song on the album, and I think it could be a fun little song on stage.
Unfortunately, they never played The Ledge live. The boot you are referring to is a Tusk Tour Rehearsal. Though it does song like Melbourne.

Tango in the Night - a Killer Lindsey song with an amazing guitar solo.
I agree wholeheartedly that it would rock, however, many would argue it would be redundant with I'm So Afraid on the setlist. I'd poo poo them, but hey, whatcha gonna do?

P.S. Speaking of Rehearsals and Straight Back, they did SB on a Mirage Rehearsal, and it does groove quite nicely. Although it would've been a bit redundant with Sisters Of The Moon at the time, they do sound eerily similar.
