Very sad news indeed :-(
...even before I got into MelodicRock etc... I was fascinated with songs like TRAGEDY and especially Robin´s Solo Outings from the early 80s - still diggin´ tunes like JULIET, ANOTHER LONELY NIGHT IN NEW YORK or LIKE A FOOL. and all the "Second Coming" BEEGEES Albums from 1987 on where pure Pop/Melodic Bliss anyway... was lucky enough to see Robin perfom live at least once during the NIGHT OF THE PROMS Tour in 2008 together with Dennis Deyoung.

RIP Robin...
