Thomas & Friends: Thomas, You're the Leader/ Roll Call Rap Extended Music Video

The Great Discovery End credits Thomas, You're the Leader, sometimes called Roll Call Rap, is a hip-hop/pop-rock styled song that plays during the end credits of the 2008 film, The Great Discovery right after the Engine Roll Call. The song is based on the Engine Roll Call, but with additional verses about the Skarloey Railway engines, the Pack, and other characters. A second altered music video was later made using footage from the thirteenth series, but in that version, Stanley, the Skarloey Railway engines, the Pack, and various other characters were cut out though, as they did not appear in the CGI series at the time. Thomas & Friends is owned by HIT Entertainment & Mattel Creations .
