One game show that used both elements (interrupted the question AND read the whole question) was the 1970's Split Second.
Whoever buzzed in first had to answer based on what little info was already given, while the 2nd & 3rd placers would get to hear the question in full, regardless of what the first person did, before they could give their answer.
That was probably one of the best Q & A buzz-in and one of my favorites since a) everybody at home could play even though one of the parts might have been answered already, and b) the fastest finger could be rewarded for their effort or could get burned.
I don't recall Monty's 1987 version stopping the question in mid-stream, though. IIRC, players could buzz in as soon as the 3 parts were revealed, and Monty read the whole question before going to the first person for their choice & answer. Just one of the many tweaks in the "Canadian" version which turned me off of that remake (that, the end game, the clouds, and Monty's blue suits).
I know its been said before, but this is one show that, if it returned to it's original format, should be revived.
