Just wanted to acknowledge Charlie's backing/harmony vocals, I have only really started to appreciate them over the past couple of years and they're great. To me they seem to be more prominent in the mix on the deluxe editions of Futurama, Sunburst Finish and Modern Music and are great on the various live recordings. I think the harmonies really add texture to the songs. Don't know if Bill created the harmonies himself, or Charlie or whether it was a team effort but on the original releases they seem very low in the mix, if noticeable at all and that's a shame.
