There’s a Beatles tribute being taped by Grammy attendees for broadcast closer to the golden anniversary of the group’s record-breaking appearance on The Ed Sullivan Show. Consequently, I’m not sure how much thunder will be generated by the appearances of Paul McCartney and Ringo Starr on tonight’s show – or even whether they will play together, or appear separately. But with Ken Ehrlich producing, the Grammys are a guaranteed must-see music event anyway, because of the live performances featuring combinations of artists. Tonight’s scheduled highlights include a duet by Beyoncé and Jay-Z, and a Highwaymen tribute showcasing surviving original members Kris Kristofferson and Willie Nelson with country stars Merle Haggard and Blake Shelton, standing in for the late Johnny Cash and Waylon Jennings.
