Question: Joseph Kahn has worked with what Star Search and Mickey Mouse Club singer?
Context: Anthony James Lucca (born January 23, 1976), is an American singer, songwriter, producer, and actor.  He is perhaps best known for starting his career on "The Mickey Mouse Club".  After the Mickey Mouse Club, Lucca went to Los Angeles, California, for a brief career as an actor, then became a full-time musician.  He is a consistent touring artist and has toured with a multitude of acts, including Maroon 5, Kelly Clarkson, *NSYNC, Marc Anthony, Josh Hoge, Sara Bareilles, Matt Duke, Tyrone Wells, and the late Chris Whitley.  He was the second runner-up on the second season (2012) of the American reality television singing competition talent show, "The Voice", broadcast on NBC. "(The) Mickey Mouse (Club) March", is the opening theme for "The Mickey Mouse Club" television show, which aired in the United States from October 1955 to 1959, on the ABC television network.  (The first two lines are: "Who’s the leader of the Club that’s made for you and me?  M-I-C-- K-E-Y-- M-O-U-S-E!")  The song is reprised with the slower "it's time to say goodbye" verse, at the end of each episode.  In the show's opening, the song is partially performed by the characters Dumbo and Jiminy Cricket.  It also ended with Donald Duck attempting to hit a gong with the "Mickey Mouse Club" title on it, but would end with comic results, such as him getting hit by lightning, or the gong turning out to be a pie, or Donald just hitting a triangle instead. James Wesley Dodd (March 28, 1910 – November 10, 1964), better known as Jimmie Dodd, was best known as the MC of the popular 1950s Walt Disney television series "The Mickey Mouse Club," as well as the writer of its well-known theme song, "The Mickey Mouse Club March."  A slowed-down version of this march, with different lyrics, became the "alma mater" that closed the show. Mickey Mouse Adventures was a comic book first published by Disney Comics from 1990 to 1991.  It featured Mickey Mouse as the main character along with other characters from the Mickey Mouse universe.  Somewhat similar in style to the animated series "DuckTales", it was based on the continuity of earlier print material starring Mickey, mainly Floyd Gottfredson's stories in the comic strip.  These stories usually featured Mickey, with the help of longtime friends Goofy, Donald Duck, Pluto, Minnie Mouse, Horace Horsecollar, and Clarabelle Cow, having adventures in or out of Mouseton against adversaries such as The Phantom Blot, Big Bad Pete, Emil Eagle, and even newcomer villains like Wiley Wildbeest, Ms. Vixen, and Prince Penguin.  The main feature was written by contemporary writers such as Michael T. Gilbert, Marv Wolfman, and others.  The back-up features were reprints of classic Mickey Mouse comic stories.  The comic ran for 18 issues from April 1990 to September 1991. Mickey Mouse: Magic Wands! , known in Japan as Mickey Mouse V: Mahou no Stick (ミッキーマウスV 魔法のステッキ , lit.  "Mickey Mouse V: The Magical Stick" ) and known in Europe as Mickey Mouse V: Zauberstäbe! , is a 1998 puzzle/action game hybrid developed and published by Kemco in Japan on December 22, 1993.  It was later published in North America by Nintendo in May 1998 in a version featuring the Super Game Boy support.  It is the fifth game in Kemco's Mickey Mouse-based video games on their "Crazy Castle" series and the only title to be released in North America under its original title. Mickey's Mouse Tracks is an American animated television series on The Disney Channel which ran from 1992 to 1995, and featured Disney cartoons and animated short films, dating from before the advent of The Disney Channel.  A similar show was "Donald's Quack Attack".  The show premiered on November 2, 1992, along with "Donald's Quack Attack", on The Disney Channel.  The show was made to replace "Good Morning, Mickey! ".  A show identical to this show called "Mickey Mouse and Friends" premiered in 1994.  It was not possible to know what episode was going to be shown on any given day, but the show "did" feature showings of some shorts that do not show up on "The Ink and Paint Club" along with some shorts made by the "Fleischer" brothers, and clips from the animated features, such as "Snow White and the Seven Dwarfs", "Pinocchio", "Dumbo", "Cinderella", and "Alice in Wonderland".  In 1996, the show was replaced by "Mickey Mouse Works", later given a plot as "House of Mouse".  In between each cartoon, a short segment featured a small clip of a Mickey Mouse cartoon, accompanied by the "Mouse Tracks" logo.  In addition to airing on The Disney Channel from 1992 to 1996, the show also ran on Toon Disney from 1998 to 1999.

She rose to prominence with her 1999 self-titled debut album that spawned the "Billboard" Hot 100 number-one singles "Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)".

A Hidden Mickey is a representation of Mickey Mouse that has been inserted subtly into the design of a ride, attraction, or other location in a Disney theme park, Disney properties, animated film, feature-length movie, TV series, or other Disney product.  The most common Hidden Mickey is a formation of three circles that may be perceived as the silhouette of the head and ears of Mickey Mouse, often referred to by Disney aficionados as a "Classic Mickey".  Mickeys may be painted, made up of objects (such as rocks, or three plates on a table), or be references such as someone wearing Mickey Mouse Club ears in a painting.  Hidden Mickeys can take on many sizes and forms. Justin Randall Timberlake (born January 31, 1981) is an American singer-songwriter, actor and record producer.  Born and raised in Tennessee, he appeared on the television shows "Star Search" and "The All-New Mickey Mouse Club" as a child.  In the late 1990s, Timberlake rose to prominence as one of the two lead vocalists and youngest member of NSYNC, which eventually became one of the best-selling boy bands of all time.  Timberlake began to adopt a more mature image as an artist with the release of his debut solo album, the R&B-focused "Justified" (2002), which yielded the successful singles "Cry Me a River" and "Rock Your Body", and earned his first two Grammy Awards.
