Thanks to all who have replied, and for your understanding about the mix-up. I certainly hope that Todd Rundgren will be around for a long time to come.
I do feel a sense of loss after my neighbor's passing, but it is seeing the grieving of his immediate family that has really been harder, and nowhere near as difficult for me as for them. He was neither ill nor what we would think of as elderly, so his death was quite unexpected, and has left a lot of people in shock. At least the healing can begin now.
The song "Lucky Guy" has long been an inspiring favorite for me, and I will always think of John whenever I hear it again.
