Sounds like it could only be one movie.
Looks like a good time for a sing-a-long kids......ready.....
In the town where I was born,
Lived a man who sailed to sea,
And he told us of his life,
In the land of submarines,
So we sailed off to the sun,
Till we found a sea of green,
And we lived beneath the waves,
In our yellow submarine,
We all live in a yellow submarine,
Yellow submarine, yellow submarine,
We all live in a yellow submarine,
Yellow submarine, yellow submarine,
