The problem with ssh arguments is that they are processed by the local shell then again by the shell on the remote host. So one often needs to escape two times.
Therefore I recommend a script that runs on one host, plus another script that loops over all hosts, each time passing the one-host script for remote execution.
Code:
  ssh "$host" /bin/bash < local_script

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
