Another one I saw today was CALLING ALL TARS, which is an extra on the DVD for the Hope/Ball movie Critics Choice. I thought that one was better than the one posted here. Berkes had more funny moments in TARS than Hope did, most notably antics in the powder room and the kitchen. Not a classic short or anything, but pretty solid, and a good way to spend 18 minutes.
Many of these Hope Vitaphone shorts have been released, but unfortunately scattered as extras on various titles. Old Grey Mayor is on G-Men. Shop Talk is on Charge of the Light Brigade (Errol Flynn film). Watch The Birdie is on Top Hat, the Astaire/Rogers film. Paree, Paree (a musical short) is on the Silk Stockings DVD. Double Exposure is on the Gold Diggers of 1935 DVD.
Most (or all) of those titles are OOP but available from 3rd party sellers for as little as $5-$10. Always fun to track down hard to see comedy shorts.
