How to define an operator to show a sequence of polymorphic things

Hi all,
I'd like to have a better way for "showing" a list of things, e.g.
show (f1 t) ++ show (f2 t) ++ show (f3 t) ++ ....
I would love to just write: (f1 # f2 # f3) t but I do not see how to
define an operator like # in Haskell without applying show over again on
the first arguments (i.e. f1 and f2). Because polymorphic lists are not
possible, I can not define # as to write [f1,f2,f3] # t either.
Any idea?
Regards, Bernd
