Eh, no more medleys for me, please. Rush hasn't done those in years, except for the "R30 Overture," so hopefully they are finished with them.
I usually only have problems with medleys if they are songs with lyrics - mashing together different songs with different lyrics makes little sense, but when it comes to instrumentals, I think it can be a creative way to present music, i.e. Dream Theater's "Instrumedley", or as you mentioned, the "R30 Overture" which, while originally were songs with lyrics, was made instrumental. I wouldn't mind something like that happening again.
But you're probably correct - I'm sure lots of Rush fans are more interested in full songs, and that being the case, I think I'd rather hear "Limbo" over "Where's My Thing?", especially since, IIRC, "Limbo" wasn't played throughout the entire TFE Tour, whereas "Where's My Thing?" was an RTB Tour staple.
