On February 9, 2014, CBS will mark the 50th anniversary of the Beatles‘ first appearance on The Ed Sullivan Show with a musical extravaganza, which is set to be recorded on January 27.

The special will feature appearances from Paul McCartney and Ringo Starr along with John Lennon‘s and George Harrison‘s widows, Yoko Ono and Olivia Harrison. Many more celebrity names are expected to be added for the star-studded bill.

Justin Timberlake, Lady Gaga, Adele, Bruno Mars, Pink and Katy Perry have all been rumoured to be preparing new performances of the five songs the Beatles played on their Ed Sullivan Show’ debut.

The special is being recorded the day after the Grammys on January 27, and set to air on February 9, although CBS has yet to confirm any of the above-named.

“Whether you were alive to witness it on television that night, or you’ve just known about it all your life, that first television appearance by the Beatles on The Ed Sullivan Show is historic,” executive producer Ken Ehrlich has declared.

“To be able to celebrate this significant event 50 years later — and to the exact day, date, and time — with an all-star cast of Grammy participants, shapes up to be one for the books.”
