....and made two calves of gold, and said unto them,
It is too much for you to go up to Jerusalem:
behold thy gods, O Israel,
which brought thee up out of the land of Egypt.
1 Kings 12:28
We have a clue as to what else the worship styles of "Egypt" involved:
...and the people sat down to eat and to drink, and rose up to play.
And when Joshua heard the noise of the people as they shouted,
he said unto Moses,
There is a noise of war in the camp.
And he said,
It is not the voice of them that shout for mastery,
neither is it the voice of them that cry for being overcome:
but the noise of them that sing do I hear.....that he saw the calf,
and the dancing:
and Moses' anger waxed hot,
Exodus 32:6,17-19
