Boyle had a great run in the 70's. In addition to "Young Frankenstein", "Crazy Joe" and "Tail Gunner Joe" he appeared in a few other really decent flicks (including "Taxi Driver") but my favorite was his role in the tv version of "From Here to Eternity" (he reprised Ernest Borgnine's part as the sargeant in charge of the stockade).

Good actor gone too soon.
