I have a feeling it was for exposure and advertising. The Smoed Show gets a lot of viewers who are young and who are probably not big Annie fans and who otherwise would not have gone and seen it on their own. The movie people were probably targeting that demographic in the hopes of the kids saying "Omg smoed did a routine to Annie, I gotta go see it. Mom, dad, I wanna go see it. Please please please." Congratulations, you just bought a family worth of tickets to Annie because of Smoed.
When I first heard that Smoed was doing an Annie promo I got excited. I thought it was going to be like when WCSS did Glee. I guess not...
