Pretty shocking news. He sure kept being crook quiet - good on him. Having lost both parents to the Big C, I just hope his passing was pain free.
It's a kick in the guts when anyone so talented leaves this planet. For me, Bowie was part of my childhood/teens in the 70's when living down the coast during my "bohemian surfer brat" period when my parents did their sea change thing. Our costal house was a Golden Fleece roadhouse and music from Bowie, Led Zep, Pink Floyd, etc, etc often thundered out of the local surfers Kombi's and Hummer vans when parked at our roadhouse. So, I had a pretty groovy childhood and Bowie was part of it. I remember back listening to "Heroes" and thinking it was the coolest song ever! Rock on Mr. Bowie - your music will travel through the universe for eternity! I hope you've hooked up with Mick Ronson and creating a storming jam session out there in the ether!
Here's Bowie and Ronson at their finest - turn your amps up to 11!
