Dolly Parton has canceled her Las Vegas residency over ongoing health issues . The 80-year-old singer had originally been scheduled to perform six shows at Caesar’s Palace last December but moved the dates to September 2026. She has now announced on social media that she won’t be able to perform as planned. In an Instagram video , Parton said that while she is “responding really well to meds and treatments” and is “improving every day”, it is “going to take me a little while before I’m up to stage-performance level”. Parton said that the meds and treatments are making her “swimmy-headed” and she can’t be “dizzy carrying around banjos, guitars and such on 5in heels”. She added: “But just think of me as an old classic car, that once restored, can be better than ever.” While September’s dates might be canceled for now, Parton also added that she is still working, including making videos and running “up and down to Dollywood now and then”.…
