Numeric equivalent of "List" formula

I figured this would be easy but i can't get it to work, basically I'm looking to list numeric values possibly with a tag. 

Basically I have two fields, lets call them Boys and Girls both numeric values
I want to show them in one field in a calendar view as: "Boys: 5, Girls: 2"

I figured you could do some kind of List("," "Boys:"[Number of Boys], "Girls:" [Number of Girls]) 
but since they're numeric it doesnt work- is there anything similar to this that will do what i want?
