Patricia Paay is a well known pop star from the Netherlands and she and her sister Yvonne Keeley were in the band Star Sisters. This is the only thing they recorded under the name the Twits and it's extremely hard to find. It appears on eBay every now and then and never goes for less than $100 because it's sought after more by Patricia Paay fans than ska collectors.
After Star Sisters broke up Patricia had a very successful solo career and even posed for Playboy a few times. She was married to American MTV veejay Adam Curry.
