Another song that would fit today is Iron Hand. But Ride Across, yes please
I have to add that I think the flute in the What It Is riff sounds very nice, though it's overused in the licks. But the riff is fine with flute, a nice touch.
Agree about Iron Hand !! Very sweet song, one of the best of the OES album (together with OES, PONO, YAYF), not played often on the OES tour, sadly left out from "On the Night" in favor of mediocre "rock" tunes like Heavy Fuel or The Bug... the flute version is very nice and would fit very well today. Same as RATR, would deserve to be resurrected.
The flute on 2008/2010 reminds me a bit of Paul Franklin's steel guitar in 91/92: the player is not the problem, the sound can be fantastic on some songs (e.g. Marbletown), but can be quite ennoying when overused to cover the guitar (e.g. WII, Speedway).
Similarly, Pedal Steel was fine on OES or The Bug, but... Pedal Steel on TR ?? on BIA ?? on Sultans ?? it's like playing accordeon on Mozart's symphonies !!
The problem may be that once you have a musician on board a tour, you feel kind of morally obliged to have him participate to all songs and not just sit there most of the time. But at times this is what PF/MM/JM should do in the interest of the music...
