And is the all-star-jam subject to a different set of legality-determining criteria than an individual band that might be performing?
No. It does not matter who performs it, just that it is performed or heard by a large group of people. You can read up on it at places like:

Here is someone that didn't have it covered (from Blabbermouth):
Steve Lynn of Glenwood Springs, Colorado's
Post Independent reports that a former local club owner reached a $40,000 settlement Wednesday with several famous musicians — including
Van Halen Music Company and
LED ZEPPELIN's
Jimmy Page,
Robert Plant,
John Paul Jones and
Patricia Bonham — who sued him for allowing cover bands to play their songs at 8150.
Steven Kovacik, former owner of 8150, called the settlement unfair.
"I don't think it's fair for one show, are you crazy?"
Kovacik said.
Van Halen Music Company and the
ZEPPELIN members were all named as plaintiffs in a lawsuit filed Feb. 16 that contended
Kovacik allowed public performances of their songs at 8150. The lawsuit, which was filed in U.S. District Court in Colorado, named
Kovacik as a defendant.
Bands like
LEZ ZEPPELIN, an all-female
LED ZEPPELIN cover band who played 8150 Jan. 15, 2006, should be held responsible for copyright infringement,
Kovacik said.
"The band is touring, making money off of
LED ZEPPELIN's music," he said. "Why should I be the one responsible to pay when
LEZ ZEPPELIN is the one playing the music?"
That's not how the law works, said
Alan Stewart, manager for
LEZ ZEPPELIN.
If stores or concert venues publicly play songs registered with the
American Society of Composers, Authors and Publishers — even on a stereo — they have to pay a licensing fee, he said
