Could Sarah Palin do for Wilson Phillips what she once inadvertently did for Adele?

Palin is scheduled to co-host NBC's "Today" show on Tuesday (April 3) morning and the one musical act booked is Wilson Phillips, who will appear in the 8 a.m. hour. The appearance coincides with Tuesday's release of "Dedicated," a collection of songs associated with the trio's parents' bands, the Beach Boys and Mamas & Papas.

Adele's career skyrocketed after she appeared as musical guest on the Oct. 18, 2008 episode of "Saturday Night Live" that Palin appeared on One of "SNL's" most watched episodes in its history, Adele credited Palin with giving her career a significant jolt after the show's airing.

Obviously, "Today" and "Saturday Night Live" appeal to vastly different audiences, but as the ratings leaders in their timeslots, gimmicks have been known to have an aftershock effect. Wilson Phillips, last seen in last year's "Bridesmaids," may well garner a healthy number of fans from the "Today" appearance.

The group is relying heavily on TV to get back into the public spotlight as "Dedicated" is their first non-holiday album in eight years. They return to "Today" on April 12 after a week of TV appearances, among them ABC's "The View" on Wednesday, CBS's "The Doctors" on Thursday, "Wendy Williams" on Friday and Saturday's "CBS This Morning."

The Palin appearance is part of a stunt-casting week among the network morning news shows. ABC's "Good Morning America" has Katie Couric as guest co-host for the week. (Disney, which owns ABC, will launch a Couric talk show in the fall). And "CBS This Morning" had an extensive interview with Oprah Winfrey on Monday that was heavily hyped in advance.

During Couric's run, only one band is booked for the morning show, Rascal Flatts on Friday.

No musical guests appeared on CBS before or after the Winfrey segment but the show did include a five-minute CMA Awards wrap-up that emphasized non-country elements such as KISS and Lionel Richie, plus the staged wedding that featured "Marry Me" sung by Martina McBride & Pat Monahan.

If the TV appearances have an effect, the results will be seen on the Billboard charts posted April 12.
