 Different theme songs have been used, depending on where, how or  when the show is viewed. In Australia, Portugal, UK, Netherlands and  other countries the theme song is Let It Ride by  Charlie Clouser (qv), while in other countries, such as the USA  and Canada, the theme song is A Little Less Conversation (the  Junkie XL (qv) mix) by Elvis Presley (qv). For the American DVD  as well as the episodes available for viewing on NBCs website, the  Clouser song is used. Occasionally, there have been different  opening songs for some episodes. For example, the Season 4 show,  "Pharoah Nuff" opened with Crazy Bitch by BuckCherry (qv).
