- Plot: This short was made for the express purpose of noting the 20th Anniversary of Warners' Vitaphone sound-on-film process and also was made to be released concurrently, and shown on the same bill, with Warners' Night and Day (1946). And that is what happened. If a theatre-goer saw "Night and Day" on first-run in any theatre, they also saw "Okay for Sound". Unless they arrived late, and then didn't stay for the "Extra Added Attractions".
