Question: Who was a member in more bands, Dave Williams or Gary Cherone? 
Context: Ray Danniels is a Canadian music executive, record producer, and talent manager.  He's the founder of SRO (Standing Room Only) Management group, as well as independent record labels Moon Records and Anthem Records.  He first rose to prominence as the manager of the Canadian band Rush and later served as the manager of Extreme and Van Halen.  His sister-in-law Kelly Carter was married to Alex Van Halen.  He was instrumental in bringing in Gary Cherone, former lead singer of Extreme, to replace Sammy Hagar as lead singer of Van Halen. David Wayne Williams (February 29, 1972 – August 14, 2002) was an American vocalist best known as the lead singer for the heavy metal band Drowning Pool. Deviations Project is a British electronic music group composed of producer Dave Williams and violinist Oliver Lewis.  The group blends elements of classical music with electronica; pieces such as Tchaikovsky's "Swan Lake", Bizet's "Carmen" and Bach's "Sonata in Gm" are recreated with modern music technology.  Contemporary compositions, including Dave Williams' own songs, John Williams’ "Theme From Schindler's List" and Fleetwood Mac's "Albatross" were integrated with classical works on the group's first full-length release, a self-titled LP.  They have also released the Christmas album "Adeste Fiddles" (a play on Adeste Fideles) and a second album, "Ivory Bow". The III Tour was a 1998 concert tour by hard rock band Van Halen.  It was the band's first and only tour with vocalist Gary Cherone, in support of the only album he recorded with the band, 1998's Van Halen III. Hurtsmile is a band fronted by Extreme singer Gary Cherone. Tribe of Judah is Gary Cherone's post-Van Halen band featuring a couple of former members of Extreme (bassist Pat Badger and drummer Mike Mangini).  An eponymous EP was released in 2001 and a full-length album was released in late 2002.  Tribe of Judah is different from Cherone's other work as it features a more industrial/electronic sound.  At least one song, "Left for Dead", was (supposedly) slated to be a track on a follow-up Van Halen album which would have featured Cherone. Gary Francis Caine Cherone ( ; born July 26, 1961) is an American rock singer and songwriter.  He is best known for his work as the lead vocalist of the Boston rock group Extreme, as well as his short stint as the lead vocalist for Van Halen on their 11th album "Van Halen III" and subsequent tour.  In recent years he has released solo recordings.  In 2007, he reunited with Extreme. Van Halen III is the eleventh studio album by American rock band Van Halen, released on March 17, 1998 by Warner Bros.  Records.  Produced by Mike Post and Eddie Van Halen, it is the band's only studio album to feature lead vocalist Gary Cherone, and the last to feature bass guitarist Michael Anthony before he was replaced in the band by Eddie's son Wolfgang in 2006.  Work on a follow-up album with Cherone commenced in 1999, but never advanced past a few demos. Exit Elvis (the flaws of non contradiction) is the first, and currently only, album by Tribe Of Judah.  It was the first full-length album by Gary Cherone after leaving Van Halen. The Best of Both Worlds is the second greatest hits album by American hard rock band Van Halen, released on July 20, 2004 on Warner Bros. The compilation features material recorded with lead vocalists David Lee Roth and Sammy Hagar; omitting Gary Cherone's three-year tenure with the band.  Prior to "The Best of Both Worlds"' release, Hagar reunited with Van Halen, and the band subsequently recorded three new tracks to include on the release.
Answer: Gary Francis Caine Cherone
