Can you sing? Do you like milkshakes? Want to be a part of a world record? If you can answer yes to at least one of those questions, I have the event for you!

Saturday at 1pm, All Steak n Shake locations in West Michigan (Grand Rapids, Holland, Kalamazoo) are attempting to set a World Record for a mass singing of "Happy Birthday"
From Brand Eatings' story "News: Steak-n-Shake - Half-Price Birthday Cake Shake, June 7, 1pm EDT"

"They will be offering a half-off discount on their new, limited-time Birthday Cake Shake to all participants. The Birthday Cake Shake is ice cream and milk blended with yellow cake and sweet buttercream frosting, finished with whipped topping and rainbow sprinkles. It normally goes for $3.49.

Why a birthday sing-along? The burger chain is celebrating its 80th birthday and expects over 20,000 customers to sing "Happy Birthday" simultaneously at its 529 US locations."

Happy Birthday to Steak n Shake!
