Jimi Jamison on Lunatica CD? Robin's soundtrack song

[Diffworlds]

Can anyone tell me which song on the new Lunatica CD Jimi duets on? I want to get it off iTunes but am not sure which one.

Also, anyone know where I can find Robin's "Gimme One Shot" from the new X-Men movie? Didn't see it on the soundtrack CD or iTunes.

Thanks,
Mike
