Near the beginning of Xanadu? Didn't sound too similar to me beyond the basic sound arpeggios have, but I was only skimming, since I don't know/like Rush.
While we're here, has anyone found a musical connection in These Walls, Never Enough or Sacrificed Sons to tie it to the title track? TROAE has the outro, TALW has the string melody etc, IWBY and PA both have musical tie-ins, but I haven't found anything in those three other songs. Maybe there's not one, but it took me so long to find the IWBY connection, that I've been wondering for a while now if there are others I've missed.
It's the nugget album, and I consider these musical nuggets.
