Looking at music from cartoon introductions

I have been searching for music to go onto my animation which I am doing with Liam, and I have found some cartoon introduction music to help me out.
Here are some introduction music to cartoons:

Tom and Jerry


Looney tunes (inner/outer) theme tune:


Looney tunes (other theme tune):


Recess (theme tune):

I think that the Recess thme tune would be best suited for our animation because of the type of music it is. The music type is like an army based tune at the beginning, so it would look good when he is crossing the tight rope.

I like all of the theme tunes, but I think the Recess one stands out. I think that me and Liam will probably look for copyright free music similar to the Recess one, as I think it will work for the type of animation it is.
