The Laurieton Plaza Theatre event has been organised by Ian Read, as a fundraiser to support the Vietnam Veterans Association of Australia.

Mr Read said the documentary film screening gives people an opportunity to celebrate the 50^th anniversary of the 1969 Woodstock music festival.

"It was held on a small dairy farm near Bethel, New York and attracted an audience of more than 400,000," he said.

"It's generally regarded as a pivotal moment in popular music history."

People are welcome to dress up to embrace their inner 60s fashionista.

"The film provides people with a glimpse of what times were like back in the 60s, to see some of the amazing bands idolised and to experience the challenges concert organisers faced when over 10 times the expected number of people showed up," Mr Read said.

The Vietnam Veterans Association of Australia supports all servicemen and women deployed on active service throughout the world.

Members conduct computer sessions for veterans, attend funerals, conduct RSL tributes and Anzac Day services.

The film starts at 6.30pm on Thursday, August 15. Tickets are $20 and available from the Plaza Theatre. No tickets will be available on the night.
