My two favourite V&M performances (as opposed to programs) will always be Mahler at the 2010 Olympics (magnified by the fact that I was lucky enough to be in Vancouver to see it live) and MR at the 2018 Olympics, but along with Mahler, my other favourite V&M FD is Umbrellas of Cherbourg (2007-08). I also thought their Russian medley when they were still juniors (2003-04) was adorable (and also super difficult for a junior team - more difficult than most senior teams were even attempting that year).
My favourite OD/SDs from them are "Puttin' on the Ritz"/"Call Me Irresponsible" from 2004-05, "And the Waltz Goes On" from 2012-13, and of course, the Prince medley from last season. I agree with a poster above who said that s/he didn't feel exhibition programs were really their strong suit, but my favourite exhibition program of theirs was "Tennessee Waltz", which I thought was really lovely.
(To digress, my other non-VM favourite all-time FDs aside from B&K's "High Society" were the Duchesnays' "Missing" and "Missing 2", B&K's 94-95 Blues/Swing medley, B&K's Riverdance, Silverstein/Pekarek's Tori Amos medley from 99-00, Belbin & Agosto's Four Seasons from their last season as juniors in 99-00, and P/C's "To Build a Home" in 2015-16. Honourable mentions to D/W's "Samson and Delilah" in 2008-09, Crone/Poirier's "Eleanor Rigby" from 2010-11, and Shibs' "Fix You" from 2015-16.)
