I want to know the name of the ESPN Sports Center theme song and who
wrote it, the one that ends da-da-da da-da-da. I would also like to
find a copy of
it online somewhere if possible. I want the full song, not just a
clip.

Thanks

I'm glad to be able to help you with this. I don't watch many sports
programs on TV, but I really like this song, and it was interesting to
learn something about the songwriter.

The theme song used by ESPN's SportsCenter was written by Annie
Roboff, who is best known as a composer of country music.

"If you haven't heard of Annie Roboff, you have undoubtedly have heard
her music... Even if you haven't gotten near country music, chances
are that you've heard her music and didn't know it.  In fact, probably
the most recognizable song to most sports fans was written by Annie. 
She wrote the original theme to ESPN's 'SportsCenter'."

"MB:    How does it feel to know that one of your songs is listened to
by so many men every single day - The ESPN Sports Center Theme?

 AR:    Well, the thing about the ESPN sports center theme, was that
it was originally music to the defunct Satellite News Channel. They
went out of biz really fast and sold that music to ESPN. I love that
so many guys know that theme...I never saw a penny from the everyday
play, because it had been sold to the Satellite News Service as a buy
out (it was the very early days of cable when no 'rules' had been
established)."

If the song linked above is the right one, I've found out who wrote
it. Just let me know whether or not that's the correct song.

Yes that is the song I was thinking of. Sorry it took me a while to
get back to you, been a busy couple of days!

Thanks

Thank you very much for the five-star rating and the nice tip!
