Geddy has virtually no voice left. The Clockwork Angels tour was extremely saddening in that respect: he was up there on stage visibly struggling to produce even a thin, weakened voice. So, even if Geddy and Alex continue as active professional musicians, it would probably be best that it not be a band format where Geddy is singing.
Sadly, the ravages of age apply to many of those other drummers that fans love to suggest for a Neil Peart replacement. John Stanier, for example, is 50 years old. That is the same age Neil Peart was during the Vapor Trails tour when some drumming obsessives noted that he was suddenly no longer as deft around the kit as he had been a decade or two before.
