Those who know me that my two all time favoutite composeres are Bach and Charles Marie Widor.
Well, imagine my surprise when looking for a recording of Widor's Marche Pontificale, I found a user who's uploaded nearly 80 vidoes of various movements of Widor's symphonies, played on Cavaille-Coll organs. Anyone in the know knows that most organist, myself included*, would have no qualms with killing a couple of people for a few hours free time on a Cavaille-Coll.( I'm lucky though, as the parish closest to mine has an organ built in 1894 with several ranks purportedly made by Cavaille-Coll. I don't know if it's true, but the 8' and 4' flutes have his characteristic sound, as do the 8' principals, and 8' Trompette.)
That said, I'll give you the pick of the litter.
