IT'S THE ULTIMATE "WHO-DUNNIT" WHEN LEGENDARY ROCK STAR ROGER DALTREY GUEST STARS ON AN UPCOMING EPISODE OF CSI: CRIME SCENE INVESTIGATION

LOS ANGELES, Oct. 11 -- It's the ultimate "Who-Dunnit" when Roger Daltrey, the legendary lead singer of the rock group The Who, guest stars in a surprise role that will keep viewers guessing, on an upcoming episode of CSI: CRIME SCENE INVESTIGATION, Thursdays (9:00-10:00 PM, ET/PT) on the CBS Television Network. The song "Who Are You," by The Who, has served as the theme song for CSI: CRIME SCENE INVESTIGATION since the show's inception in 2000.

Roger Daltrey has been a world-famous star since the early 1960s when he began his career as the lead singer of The Who, and has since become one of the most popular vocalists in rock music history. The band has sold 100 million records, toured the world several times, including gigs at New York's Metropolitan Opera House and Carnegie Hall, and has been inducted into The Rock 'n' Roll Hall Of Fame. Daltrey has also enjoyed a very successful solo career that yielded several hit singles and has maintained a successful acting career since the 1970s. A Golden Globe nominee for his portrayal of the title character in "Tommy" (the film adaptation of The Who's famous rock opera), he `has amassed a multitude of film and television credits, ranging from Shakespeare's "Comedy of Errors" and Jonathan Miller's "The Beggar's Opera" to the television show "That 70's Show." He has also completed filming for "Extreme History," a series for The History Channel. His theater credits include "A Christmas Carol" and "The Wizard of Oz." Daltry is currently on a major worldwide tour with The Who, promoting their current album, "Endless Wire."

CSI: CRIME SCENE INVESTIGATION is a fast-paced drama about a team of forensic investigators trained to solve crimes by examining the evidence. They are on the case 24/7, scouring the scene, collecting the irrefutable evidence and finding the missing pieces that will solve the mystery. Gil Grissom, shift supervisor, heads the team of investigators at the Crime Lab in Las Vegas. The team includes Catherine Willows, a hard-working single parent with a checkered past and a teenage daughter she's raising on her own; Warrick Brown, a top analyst with insider knowledge of the gambling world; Nick Stokes, a true-blue stand-up guy who empathizes with victims via his own experiences; Sara Sidle, a dedicated and inquisitive investigator who has more than a professional interest in Grissom; and Greg Sanders, the wacky tech analyst turned field investigator. The CSI team members also work closely with Capt. Jim Brass, the former chief, now assigned to Homicide, and Dr. Albert Robbins, the ever-professional medical examiner. They are also supported by David Hodges, a lab technician with a specialty in trace and foreign-substance analysis, and Sofia Curtis, a former officer-turned-CSI, whose frustration with lab politics has led her to return to the police force.
