2010-2011 - First season under Nikolai Morozov.
SP Music: "Tango de Roxanne" from the Moulin Rouge soundtrack
FS Music: "Piano Concerto No. 3" by Sergei Rachmaninoff
2011 Russian Nationals -- Sergei was out much of the season due to injury, but he managed to place 4th here and bounced back from 10th place after the SP with a 3rd place FS.
The SP is not available on video (or I haven't found it anyway)
Sergei debuted the "Tango Roxanne" program at a show in Latvia:

AFAIK, the only time he may have used it in international competition would have been the 2011 Winter Universiade. Of course there are videos for his FS and gala from the Universiade, but none for the SP that I could find.
Also, at 2012 Worlds he used a different SP, "Artsakh" by Ara Gevorgyan. I don't know offhand if he skated this SP anywhere else.

Ok, I don't want to overwhelm the thread with every video and interview he's ever done, but I have collected quite a lot and this is the edited version

(I tried not to duplicate anything
Mrs. P already posted...btw, I don't know how you and
dorispulaski do it, because I had these saved already & it still took me ages to put them in a somewhat organized list):

edit - he also has a fanpage on VK, but it's very quiet...I'm not sure why

Maybe people just use the page for Eteri's group, which is pretty active.
