The 50th anniversary of the Beatles' groundbreaking performance on The Ed Sullivan Show is to be commemorated with a two-hour U.S. Tv special next year (14).

The Night That Changed America: A Grammy Salute to the Beatles will be broadcast at 8pm on 9 February (14) - 50 years to the day and time of the Fab Four's American Tv debut, which was watched by more than 70 million viewers.

The new special will be filmed in January (14), the day after the Grammy Awards, and it will feature yet-to-be-announced modern artists performing the tracks the Beatles played during the Sullivan broadcast, as well as other hits. The show will also include archival clips and footage from the Sullivan show.

It is not yet known if Sir Paul MCCartney or Ringo Starr will be involved in the special.
