Our music lab guys are getting baked and listening to classic rock again, and just now they sent up this clip of Dutch progressive rock group Focus performing their hit song, “Hocus Pocus,” in 1973. I’d forgotten how amazing this band was. Jan Akkerman? The king of rock guitar. I’d also forgotten about the glory days of rock when yodeling and flute playing could stand shoulder to shoulder with heavy-duty balls-out guitar-based rock. Not to mention wild facial expressions. If you can stand to watch the entire thing you should check out the wild response from the crowd. I mean they were just loving it. See, the pot wasn’t as strong in those days, but people smoked a lot more of it. I think. Best of all, Thijs van Leer, the yodeler, now looks like this.
