Philip Chapman Lesh (born March 15, 1940) is a musician and a founding member of the Grateful Dead, with whom he played bass guitar throughout their 30-year career. After the band's disbanding in 1995, Lesh continued the tradition of Grateful Dead family music with side project Phil Lesh and Friends, which paid homage to the Dead's music by playing their originals, common covers, and the songs of the members of his band. Lesh operates a music venue called Terrapin Crossroads. He scaled back his touring regimen in 2014 but continues to perform with Phil Lesh & Friends at select venues.
Lesh was an innovator in the new role that the electric bass developed during the mid-1960s. Contemporaries such as Casady, Bruce, James Jamerson and Paul McCartney adopted a more melodic, contrapuntal approach to the instrument; before this, bass players in rock had generally played a conventional timekeeping role within the beat of the song, and within (or underpinning) the song's harmonic or chord structure. While not abandoning these aspects, Lesh took his own improvised excursions during a song or instrumental. This was a characteristic aspect of the so-called San Francisco Sound in the new rock music. In many Dead jams, Lesh's bass is, in essence, as much a lead instrument as Garcia's guitar.  Lesh was not a prolific composer or singer with the Grateful Dead, although some of the songs he did contribute--"New Potato Caboose", "Box of Rain", "Unbroken Chain", and "Pride of Cucamonga"--are among the best-known in the band's repertoire. Lesh's high tenor voice contributed to the Grateful Dead's three-part harmony sections in their group vocals in the early days of the band, until he largely relinquished singing high parts to Donna Godchaux (and thence Brent Mydland and Vince Welnick) in 1976 due to vocal cord damage from improper singing technique. In 1985, he resumed singing lead vocals on select songs as a baritone. Throughout the Grateful Dead's career, his interest in avant-garde music remained a crucial influence on the group.  In 1994, he was inducted into The Rock and Roll Hall of Fame as a member of the Grateful Dead.

Late Night with Conan O'Brien is an American late-night talk show hosted by Conan O'Brien that aired 2,725 episodes on NBC between 1993 and 2009. The show featured varied comedic material, celebrity interviews, and musical and comedy performances. Late Night aired weeknights at 12:37 am Eastern/11:37 pm Central and 12:37 am Mountain in the United States.
The show's house band was The Max Weinberg 7, led by drummer Max Weinberg, who also served as a sounding board for O'Brien on the show (more so after Andy Richter's departure). The other six members were Mark Pender on trumpet, Richie "LaBamba" Rosenberg on trombone, Mike Merritt on bass, Jerry Vivino on saxophone and brother Jimmy Vivino on guitar, and Scott Healy on keyboards. James Wormworth served as backup drummer when Weinberg went on tour with Bruce Springsteen. With the departure of Andy Richter, Max Weinberg assumed a bigger role as an interlocutor for O'Brien's jokes. One common running gag was Max's awkwardness on camera and his apparent lack of chemistry with Conan. Weinberg was often used in sketches as well, which usually revolved around his purported sexual deviance (mostly a penchant for bedding barely legal groupies), although long-running sketches also spoofed Max's lack of knowledge of current affairs.  "LaBamba" was also used as the butt of many of Conan's jokes. These humorous sketches usually revolved around LaBamba's sizeable mustache, his poor acting skills, and his alleged inability to read written music. Mark Pender would often sing songs on the topic of a current event which ended with him screeching uncontrollably and climbing the risers into the audience. All members of the 7 had successful side careers as studio musicians.  As is common in the talk show format, the Max Weinberg 7 performed the show's opening and closing themes, played bumpers into and out of commercial breaks (they actually played through the entire break for the studio audience), and a short piece during O'Brien's crossover to his desk after his monologue (except for several months beginning in April 2008, where a commercial break was inserted at that point). The show's opening theme was written by Howard Shore and John Lurie (a finalist for the job as band leader). The show's closing theme was called "Cornell Knowledge", and was lifted from Jerry and Jimmy Vivino's first album together. However, on Late Night, it was played at a much quicker tempo than the album version.  The band played a wide variety of songs as bumpers--usually popular music from a variety of eras. Weinberg sometimes took extended leaves of absence to tour with Bruce Springsteen as the drummer for his E Street Band. During his absence, temporary replacement drummers were hired (most commonly James Wormworth), and the band was led by Jimmy Vivino ("Jimmy Vivino and the Max Weinberg 7").

Who is LaBamba?
These humorous sketches usually revolved around LaBamba's sizeable mustache, his poor acting skills, and his alleged inability to read written music.
