Command to list Branches on a specific Remote (i.e. select from rtb's)

[Philip Oakley]

Hi,
I'm unsure if there is a command for this.

Currently I have 1600+ remote tracking branches (rtb) for my Git repo as 
it covers both git.git and git-for-windows and some other contributors.

Finding a specific rtb for a particular remote looks like there ought to 
be a simple command ready to do the job, but I haven't found anything.

Is there a command or simple simple invocation of branch, show-ref, 
for-each-ref, etc that can be give a branch pattern and remote name to 
quickly filter down the list of potential branches to just one or two 
24-line screens?
