It’s exciting but sad: Lady Gaga and Tony Bennett will reunite for the last time to perform together. “One Last Time: An Evening with Tony Bennett and Lady Gaga” is going to be a 2-night show at New York’s Radio City Music Hall. The show will start on August 3, which is Bennet’s birthday, and end on August 5.

As the artists are requesting, no cell phones, cameras, or recording devices will be allowed. Upon arrival, all electronic devices will be secured in Yondr pouches that will be unlocked at the end of the event. For attenders, upon entry, you must provide proof to show you’re fully vaccinated against COVID-19. The only exception is children under 16 years of age, who can enter with a negative antigen or PCR Covid-19 and are accompanied by a fully vaccinated adult.

Early this year, Bennett’s family first revealed that he was diagnosed with Alzheimer’s in 2016. With doctors’ encouragement, the Grammy-winner continued making music and tours. Though his condition progressed slowly with intervention in the past few years, The Radio City concerts will be his last show.

In 2014, Gaga and Bennett released Cheek to Cheek which earned them the Grammy Award for Best Traditional Pop Vocal Album. This year, the two stars made a second album together, which will be released later this year.

Citi cardholders have early access to presale tickets on July 21st from 10 a.m. to 8 p.m. local time. Tickets for the shows will go on sale Thursday, July 22, at 10 a.m. local time via Live Nation.
