When rumors began circulating that Geddy Lee and guitarist Alex Lifeson might return to music without their longtime Rush bandmate Neil Peart, an obvious question sprung to mind: Who would replace the presumably retired drummer?

Then other considerations came into play. Who's to say that Lee and Lifeson would stick with the tried-and-true trio format in place since Rush was co-founded back in 1968? This potential new group could easily expand to accommodate various new instrumental and vocal contributors. That's certainly been the case with Lee and Lifeson's musical output away from Rush – rare though it may be.

Those earlier projects might provide some sense of where their next musical adventure could be headed – and they might even provide clues as to possible new outside collaborators. (Rush occasionally invited others into their sessions, as well.) Whatever they decide to do, word is that the new project wouldn't be called Rush, even though the band was actually started years before Peart's arrival.

Instead, the remaining duo is said to be considering LeeLifeson as a band name. That represents the potential for an exciting new beginning, even as they smartly preserve the legacy of a threesome that was inducted into the Rock and Roll Hall of Fame in 2013.

Like most lists, the above 24 Potential Collaborators for Rush's Geddy Lee and Alex Lifeson contains suggestions that range from entirely reasonable to somewhat unrealistic to downright ridiculous. But that's the fun of it, you know?
