For the 25th anniversary of The Simpsons, the merchandising machine behind the show has been going all out with an FXX marathon, Hollywood Bowl concerts, cosmetics, and the release of collectible figures of various guest stars. Today The National Entertainment Collectibles Association and Twentieth Century Fox Consumer Products announced the fourth wave of these “25 Of The Greatest Guest Stars” toys, which includes Elvis Costello, “Weird Al” Yankovic, Aerosmith, and Tom Jones. They’ll join the already released Springfield figures of R.E.M., the Who, Kid Rock, James Brown, and Britney Spears. (They’re not all musicians: you can get Mark Hamill and Tony Hawk, too, among others.) You can check out a gallery of some of these collectibles above and buy them for your dorm room at Toys “R” Us. Our list of the show’s 10 Greatest Rock Moments can be argued about here.
