PA Musical PowerHorn. $39.99. Er..so there’s a reason why you would need to buy a megaphone which comes with 94 built in songs, isn’t there? Isn’t there?

‘This portable PA system plays 94 built-in tunes — everything from major college fight songs to nostalgic favorites, Christmas carols and children’s songs. Plus, you can program up to five more tunes yourself with the keypad, or use it as an organ.’
