I heard this song played on the radio.
I heard this song (finite clause)
So 'I heard this song' feels like it requires more information alone, but you could say it in speech or:
I heard this song. It was played on the radio.
I heard this theatre now shows films.
You can't hear the theatre in this sense, but as written, do we still class it as finite clause?
Could you have:
I heard this theatre. It played such loud music.
