Geddy Lee and Alex Lifeson have dipped into their personal collections in order to give Rush fans a chance to own pieces of the band's history while supporting a great cause.

It's all part of their Grapes Under Pressure 3 charity auction, which started Oct. 3, runs through Oct. 13 and supports Grapes for Humanity Canada, a charity that seeks "to provide a better quality of life for victims and survivors of disasters" by raising funds "through various international wine events, wine auctions, corporate and private home wine tastings." To that end, Lee and Lifeson have donated an array of Rush-related items that includes:

A Geddy Lee Fender Jazz bass AND a rare Garrison G-50E Custom Acoustic guitar used by Alex on the Snakes & Arrows tour. They have both been signed by Geddy and Alex as well as by members of Depeche Mode, TOOL, the Fray, Pearl Jam, Judas Priest and many more in Support of Grapes for Humanity.
A Gibson Les Paul Axcess “Custom Shop” guitar which was used by Alex Lifeson in a recent secret session. The guitar will be autographed and will be accompanied by a signed photo of Alex with the Guitar.
A Sabian Paragon Diamondback Chinese 20″ Cymbal, from Neil Peart’s personal kit, with Neil’s signature.

The auction, which you can watch or bid on here, comes just a few weeks after the third annual 'Geddy & Alex's Excellent Harvest Adventure,' during which the duo boarded a train with a lucky group of fans (each of whom paid $1,250 a ticket for the privilege) for a day of wine country fun. With days to go before Grapes Under Pressure 3 comes to a close, the memorabilia on offer -- which really includes quite a bit of cool stuff, with the above items representing only a fraction of what's for sale -- has already racked up thousands of dollars' worth of bids. All proceeds have been pledged to rebuild health care facilities in the Philippines damaged by the Haiyan Typhoon.
