He recounted how, after gang-related insults were screamed at them and returned, a young man ran up the drive and smashed a car's back and front windows with a baseball bat.
He told prosecutor Andy Hill he now knew that man was Cramer McMeeking.
"George Jolley had a gun with two barrels, he walked forward, pulled his cap down, aimed and 'woomph'."
"I was thinking 'Am I in a dream, what is happening?'" Witness A said.
He recounted how as he handed a steel pole to his companion, George Perham, George Jolley again raised the gun, pointing it at him, but it didn't fire.
Witness A said Perham had gone looking for George Jolley while he attempted to find a friend of his, telling a police officer he encountered his mate needing help.
"George [Perham] would have wasted me if he saw me talking to a cop. He said 'Don't you f***** open your mouth' but I gave the cop a few names."
Questioned by Jolley's lawyer, Sam Wimsett, Witness A said he'd recognised George Jolley as the shooter because he knew his eyes.
"We've been in altercations before," he said.
"Ever since that day you have lied about Hori George (Jolley) haven't you?" asked Mr Wimsett.
"On the Bible and swearing by Almighty God I have not," replied Witness A.
The trial continues.
