Thomas And Friends Season 1-7 (Fan-Made) Ending

Here is another Thomas Song Mashup that I did quite a while ago now, which is 'Little Engines', one of the Classic Songs from Series 6. This also features the vocals of Mike O'Donnell, who wrote this song along with Junior Campbell. You'll notice a slightly higher pitch to the song as well. I feel it gives it just that little bit  more bounce and energy. 

'They're not such little engines after all!'

Little Engines - Original/Mike O'Donnell Song Mashup

So, I was on soundcloud the other day and I saw that Sol did a version of Thomas' season 1 theme with proteus instruments layered on top. It was very inspiring so I redid thomas' s2 theme and then I added proteus instruments on top and It sounds splendid. Enjoy!

Thomas The Tank Engine's Theme (Series II Freelance)

Thomas' Theme in Series 5 is a rather nice variation, it feels as if the music has matured with the series and the character as it takes a more classical approach compare to it's more upbeat style in previous arrangements. This mix has the classic bridge section incorporated into the S5 mix to give it the feel of a full extension of Thomas' Theme from that season.

Happy Halloween!  I know it's still a few days away, but who cares!  I made this for my friend Great Western Legacy's upcoming adaptation of Duncan Gets Spooked and seeing as Duncan Gets Spooked is in vogue this year, I thought I'd post it.  Be sure to keep an eye out for it sometime after Halloween, 'cause it's gonna be awesome!  Enjoy!
