Python Format String with List

I want to format a string in Python, and as one element have every element of a list, for example below

mylist = ['john','phil','ted']
var1 = 'xxx'
var2 = 'zzz'
'{0} bla bla bla {1} bla bla {2}'.format(var1,<every item in mylist>,var2)

Basically what I am after is

xxxx bla bla bla john phil ted bla bla zzz
