As the Post’s Lisa de Moraes points out in her recap of the finale, “Idol” finalists and previous contestants got to perform with some big name musicians, including Tim McGraw, TLC, rapper Lil Jon and even actor and Tenacious D member Jack Black.

But I’m betting, based on Google trends, quite a few people who watched the finale didn’t know who Tom Jones was, as he performed “It’s Not Unusual.” I guess kids these days are too young to remember Carlton Banks getting down to the song on “The Fresh Prince of Bel-Air.” Crooner Tony Bennett also made an appearance on “Idol,” and now on Google, singing “Steppin’ Out With My Baby” with Haley Reinhart.
