For the record members appearing last night (as I remember it) and what they were playing:

Kevin Drew – Guitar/Synth/Vox
Brendan Canning – Bass/Guitar/Vox
Justin Peroff – Drums
Charles Spearin (Do Make Say Think)- Guitar/Bass/Vox/Trumpet/Synth
Andrew Whiteman (Apostle of Hustle)- Guitar/Bass/Vox
David Newfled (Producer)- Guitar
Leslie Feist (Feist)- Vox/Drums/Guitar
Evan Cranly (Stars) – Trombone/Guitar
Amy Milan (Stars) – Vox/Synth
Ohad Berchetrit (Do make say think) – Guitar/Bass/Drums/Synth
John Crossingham (Raising the Fawn) – Guitar/Bass/Saxophone
Lisa Lobsinger (former- Reverie Sound Review) [she has awesome hair] – Vox
Bill Pridle (former- Treble Charger) – Guitar
Julie Penner – Violin/Vox
Martin Davis Kinack – Sound (very important when you have all the above at once)

Sadly Jason Collett, Emily Haines (Metric), James Shaw (Metric), K-OS nor Murray Lightburn (The Dears) appeared to reprise their roles from broken social scene recordings.
Also there were at least two people I had no idea who they were- a man and a woman playing trumpets and nothing else except maybe backup vox.
