If you still want to believe it is Liz, well, that certainly is your right but already thousands have seen it in a week and agreed. It is Lisa.

Well, Sorry but Captain Obvious is wrong. No doubt that Liz Agriss Derringer was Ricks first wife, if you look at the pictures you posted and at the girl you will see there is no resemblance. However, if you watch the proof on the new video about Lisa Leonard Dalton, you will find the she is indeed the real Sloopy Girl Dancer. [url redacted]

Please be sure to check out the video that will be released sometime this month, Aug 2021 that will show you the identity of Sloopy dancer. BTW, Liz was only 5'2", the lady in the video is 5'7". You should not only be satisfied but happy to see the really Sloopy dancers story.

There is new evidence to prove the identity of the Sloopy Girl Dancer. It is NOT Liz Agriss Derringer (Rick's ex-wife) nor is it Liz Brewer, the lady from Britain. It also is not Lisa Dalton that is a showgirl dancer who you can google.
It is however, Lisa Leonard Dalton, and sometime soon, Aug 2021, the video evidence and her story will be released. You can go to YouTube sites that show the video and as soon as it is completed, it will be linked there.

So..., Is this a

It's so close, it smells like a dupe.

Did some research and @CaptainObvious is right, Sloopy is Liz Derringer, guitarist Rick Derringer's first wife. Here are photos of her I think from the 1970s, which I'm embedding for posterity (and SEO):

from Urban Dictionary :
"
The year is 1965 and an almost unknown rock band from Ohio called The McCoys recorded a song called "Hang On Sloopy."

"Hang On Sloopy" was inspired by a woman named Dorothy Sloop who was a native of Steubenville, Ohio. Apparently she had a career as a singer in the 1950's and used the name "Sloopy" as a stage name. Dorothy Sloop passed away in Pass Christian, Mississippi. Her song will long live on in the hearts of people for years to come....

hang on sloopy, sloopy hang on...
"
(the other definitions are par-for-course)

Sloopys' been here before....

So..., A video about a girl named Sloopy shaking her... um, Hair?

Mixes well with Hang on Sloopy...

Very surprised this has so many votes. The title is wrong, the footage is sloopy, the background music is weird and isn't that impressive to begin with.

Thank you Swampgirl, I know that It's all part of my cunning plan: I'm saving up my vote,in case my vid gets nearly enough votes to get out of the queue,but remains stuck - I'm there...
...if i don't screw up remembering queue expiration time, that is

...and "Eyes without a face" is really worth seeing - the WHOLE movie
