After Barnard's Convocation, the OLs and RAs of BC led the 11s in a sing-a-long tribute to the musical stylings of Rihanna:

"When the sun shines we'll shine together

We will love Barnard forever

Columbia will always be our friend

Our partnership will go on till the end

2011 is better than ever

All the classes will stand together

You can stand under our umbrella

You can stand under our umbrella"

...ella, ella, ella, eh, eh!
