Get wmic to read a file with multiple hostnames and output who is logged on

I am looking for a way to get WMIC to read a file will a list of hostnames and to return the currently logged on user if any.

At the moment I am just using wmic /node: "hostname" COMPUTERSYSTEM GET USERNAME.

This works fine for a single system, I would like to do it for nine and have the output look as such

hostname username

hostname username

or 

hostname

username

Thanks
