There's an example of play in Moldvay BD&D which is clearly based on the one in OD&D, but a lot more detailed. Unfortunately it's too long to reprint it here, it's over a page, but it's good stuff, far superior to the original imo. There's actually some roleplaying in it (in the sense of speaking in character) for one thing.
As an aside, I think Moldvay BD&D may be the first TSR publication to promote roleplaying in this sense, it does so in several places. It was probably the source of the concept in my group. We certainly regarded it as a desirable thing, even aged 11.
There is a caller but she is a much more consensus-seeking leader than the one in OD&D. The other players are asked if they have no objections to going in a particular direction. They even get to talk!
They still avoid the silent door, killing the monsters (this time goblins) behind the noisy door. They still know about magic cloaks and boots.
But probably the best bit is -
DM: "Black Dougal gasps 'Poison!' and falls to the floor. He looks dead."
Fredrik: "I'm grabbing his pack to carry treasure in."
Cold mang, real cold.
