Luke's English podcast is a journey into the DNA of the English language. So that was the LEP jingle megamix that you heard at the end there. If you'd like to know where all those little samples in that jingle come from, check out the jingles and music category in the Luke's English podcast app. There's a full episode there in which I go through all the samples and explain where they all come from. And it's called deconstructing the LEPJingleMegamix.
