It seems Olivia Newton John’s three year run at the Flamingo in Las Vegas may be over as her available dates this Summer don’t line up with the available dates of the Flamingo showroom. The Australian star who became known worldwide because of her lead role in the movie Grease with John Travolta, is currently on a tour through May. The busy performer recently wrapped up a tour of the UK and has other projects including recording a new album as well as a movie planned in the near future.  Olivia Newton John’s last performed the show in December and, would perform at the Flamingo on the open nights when Donny & Marie weren’t performing in their showroom. It’s a shame that the Summer Nights show won’t be returning to the Flamingo this year as it generally was well liked by people that had seen the show. If Olivia Newton John isn’t able to perform this year in Las Vegas hopefully Summer Nights show will return for another run in 2018.
