The Thomas & Friends episode "Jack Jumps In", when released in the US in 2004, was released on the DVD/VHS "New Friends for Thomas". This DVD/VHS was unique in that it was the only DVD/VHS to be narrated by long-time UK narrator Michael Angelis - this release being in-between the hiring of Michael Brandon and the leaving of Alec Baldwin as the narrator in the US. This episode along with "A Friend in Need" was narrated by Alec Baldwin, however, for consistency reasons, Michael Angelis' UK Narration with some dialogue redubbed by Angelis was included.
The original Alec Baldwin narration for "Jack Jumps In", along with "A Friend in Need", was last heard when the whole episode was shown on May 16, 2006, on TVOntario in Canada.  Two recordings of the episodes from this airdate had popped up on YouTube in '06, before being privatized in 2007. These uploads were both of exceedingly poor quality, being filmed in front of a TV.
"A Friend in Need", the second part of this episode, was released with Baldwin's narration on the DVD "Mud, Glorious Mud" on May 6, 2008. However, "Jack Jumps In", despite being the first part of the story, was orignally never given an official release with Baldwin's narration, until it was finally released on the Amazon Instant Video release Thomas & Friends Classic Volume 6 in May 2016.
On July 5th, 2014, a low quality version of Baldwin's narration was uploaded to Dailymotion. A higher quality version was then uploaded on October 5th, 2014, by TTTEArchives.
