For us we had serenades for informal and formal occasions. We sometimes would serenade on spur of the moment to one of our brothers girlfriends or to some hottie out on the town. We also had serenades occasionally when we would organize a serenade with a sorority and the pledges would accompany with us(we'd wear our kelly green sports jackets and bring a rose). Other Formal occasions included semi formal or formal when we would all get down on one knee and serenade all of our dates. Lots of fun
A VT Theta(Sandy) one time told me that they had a serenade that they made for especially for the betas and it sounded really cool. I believe they had a mixer when they did that.
