Barrel Brothers Root Beer Creamy Vanilla

In the Rocky Mountains the Brothers of Barrels did live.
Each with their own gift to the world to give.
Martin with a root beer that was very plain,
and decent cream soda was created by the brother Shane.
Why don't you mix the two together their father did suggest.
The creator of Apple Beer the brothers could not protest.
Now the sum is certainly better than the parts,
but the mixture didn't quite capture the Thirsty Dudes hearts.
While our interests the vanilla cream did pique,
the root beer was a bit watered down and weak.
