I think you might find the following blog post helpful:
http://blog.jayfields.com/2011/01/clojure-select-keys-select-values-and.html
What you are asking for is basically (clojure.string/join (select-values
my-map vals)) where select-values is defined in several ways in the linked
blog post.
For code golf points, the briefest example from the blog that would work
for your purposes might be:
(defn select-values [m ks] (map m ks))
So:
user=> (def my-map { :name "roelof", :city "big-secret" })
user=> (clojure.string/join ", " (map my-map [:name :city]))
"roelof, big-secret"
