Which sends me back to a personal favourite, Ronnie Hudson And The Street People's "West Coast Poplock", which borrows a chunk of Zapp, and adds the iconic lyric "California knows how to party" : ttp://www.youtube.com/watch?v=bmJXjDhpA\\... Documentary evidence of real-life poplocking to Ronnie H can be found here: ttp://www.youtube.com/watch?v=02HxXrVlr\\... The Hudson lyric was later, of course, borrowed by 2pac's "California Love", which featured Zapp's Roger Troutman: ttp://www.youtube.com/watch?v=FWOsbGP5O\\...

With this dense web of connections, moving both back and forth along the timeline, "West Coast Poplock" seems something like the keystone of hiphop, a crucial multi-way node in rap history. But perhaps out there is the another track which has even more points of connection -- the Higgs boson of
