Starr, who is promoting his new album, Liverpool 8, planned to perform the title song with fellow rocker Dave Stewart. However, due to miscommunication between his publicist, Elizabeth Freund, and the musical director, Starr didn’t realize the performance had to be 2 1/2 minutes or less, Freund told The Associated Press.

When told Tuesday morning that the performance had to be shortened, Freund said Starr tried to cut about a minute of the song’s 4 minute, 15 second length, down to 3 minutes and 30 seconds. However, according to Freund, producer Michael Gellman said it had to be less than 3 minutes.

“We offered to cut back our chat time and asked them to fade or go to commercial. They were not willing to do that and Ringo was not willing to cut it further, so without a compromise we were not able to stay,” Freund said in a statement to The Associated Press. “Ringo left saying, `God bless and goodbye. We still love Regis.'”

A spokeswoman for “Regis and Kelly” told the AP the show’s producers tried to work with Starr, noting his appearance had been booked since November and the time requirement for the song – the show’s standard – had been expressed numerous times.

With Starr absent, fashion designer Michael Kors and the winners of CBS’ “The Amazing Race” did extra segments to fill his time.

Starr, 67, shortened his song for CBS’ “Late Show With David Letterman,” but it was still over 3 minutes, Freund said.
