We did tackle a similar question awhile back (12/16/2006, to be precise), but there have been some changes and updates since then, so it felt timely to readdress this query.
The Las Vegas Walk of Stars was established by the Motion Picture Hall of Fame Foundation, which is "an institution dedicated to the preservation and memory of the best of the best in the motion-picture industry" and occupies a four-mile stretch of sidewalk on both sides of the Strip, from Sahara Avenue to Russell Road. It honors "people of prominence in entertainment, sports, literature, the military, and humanitarian and civic fields."
Each actual star consists of a three-foot-square slab of polished granite weighing up to 350 pounds and inlaid with the recipient's name and specialty. The WOS' first inductee was Wayne Newton, honored in October 2004; his star is outside the New Frontier, where Newton performed for 15 years.
Back in 2006, when we previously answered this, the latest people of prominence to be inducted were the Society of Seven (on Nov. 28 of that year), who'd been performing in one incarnation or another for more than 30 years. Their star is in front of the Flamingo but in April, 2008 the group played its last gig in that showroom. One member of the cast, however - singer Lani Misalucha - is currently performing in the show Voices at the Las Vegas Hilton (so plurally named because originally she performed alongside Earl Turner, who left unexpectedly), while the remainder of Society of Seven, plus a new female vocalist, are enjoying an extended run at Gold Coast through March 28.
More recent inductees now include Elvis (Sept. 2008, located outside the Riviera), show producer Dick Feeney (Oct. 2008, New York-New York), Bobby Darin (May 2007, Flamingo), and Sammy Davis Jr. (Feb. 2007, Riviera).
Other inductees include Siegfried and Roy, Liberace, Rich Little, and Wayne Allyn Root (author of The Zen of Gambling and one of the most recognized professional sports prognosticators in the world).
The list of nominees has several hundred names on it in total and up to 3,000 oould eventually be installed. Currently, there are 36 inductees. Click here for information about the criteria for nominating an artist or sponsoring a star, which involves a donation of $20,000.
