John Tesh is a badass ... not just 'cause he WROTE that insanely catchy/iconic/awesome NBA theme song "Roundball Rock" ... but 'cause he performed it in the middle of the street for us yesterday.
Tesh was out in Beverly Hills when we struck up a convo about the greatest TV theme songs of all time ... which don't contain lyrics. Naturally, "RR" is on the list ... along with a classic from the '60s ... and Tesh gives us a musical sample of that one, too.
Bonus: In case you haven't seen the clip of Tesh explaining how he came up with the music for "Roundball Rock" ... check out the clip below. It's worth it.
