I had this problem. 
My solution came without removing the horn button. The horn wire exits
the steering column under the dash. Remove the plastic trim under the
column.  At the base of the column you'll see the horn  wire connection
( white I think) coming out of the column. The spade connection on this
wire was shorting on my '82. 
Otherwise previous suggestions for removal of horn button are right on
the money.

Yup, you are grounding out in the steering column.
When you press the horn, you are supplying ground to
the horn (juice is supplied whenever the key is on).
That ground wire runs up the steering column and
connects on the underside of the horn plate/button on
the steering wheel.  Pull the horn plate/button and
look at the wire plugged into it.  Check if there are
any bare spots where it comes out of the column.
