The Tamworth country trio know how to welcome in the New Year and they'll be celebrating in all their ghastly glory with A Ghostly Haunted House Party at the Tamworth Services Club.

This is the seventh year of their free, themed New Year's Eve parties, which have become a tradition in Tamworth.

The three band members Carolyne Morris, Wendy Wood and Kerry Walsh said they "tossed around a few ideas" and settled on the ghostly theme.

Morris said one reason the theme was chosen was because it was easier to get enough Halloween decor items to fill the big space at the club.

"It's not too scary, because not everyone likes really spooky things," Morris said.

"It's become a bit of a fun tradition for Tamworth."

The trio will be dressed up as zombies, Frankenstein's bride and other ghoulish characters, and would love the audience to join them in the frivolity.

Morris said she hoped Frankenstein would make an appearance, because she was going as his wife.

The night will be special for many reasons, not the least of which is Those Gals don't get together very often these days.

"We've had wonderful support from the Facebook community, who donated milk bottles that are being used as table decorations," she said.

The decorations will be extensive, including their own custom coffin, skulls, large masks and plenty of costumes.

"We always have a photo booth for people to use and games," Morris said.

"It's BYO headstones and we hope the staff dress up."

Walsh said people loved the New Year's Eve dress-up parties.

"It's a chance to dress up, have fun and let your hair down," she said.

The trio said they hoped it would be bigger and better than ever this year.

"We love to have a bit of fun and see how other people dress up," Walsh said.

"I enjoy seeing what people's imaginations are like."

Morris said she enjoyed the colour and light of the New Year's Eve parties.

The night will include games, the photo booth and plenty of table decorations and decor around the ground floor of the Tamworth Services Club.

Festivities begin at 8pm and run until ... next year.
