Sure, everyone knows that Ken's theme is influenced by Cheap Tricks "Mighty Wings". However I rarely see people noticing that Guile's theme is quite influenced by someone else's work too. I only discovered this last year and have since became a huge fan of the work by Japanese jazz fusion band T-Square. Please enjoy their live performance of "Travellers" in 1984:

In case you never heard it before, your mind will blow at about 1:20. Guess T-Square "Travellers" goes with everything! Thank you "Street Fighter 2", after all these decades, you just keep on giving.

*OMAKE* The studio version.
