Mike Cotton of The Tubes Project just sent me an email announcing that the Bill Graham archive has added The Tubes New Years Eve 1975 show:
This is the “Big Bang” for us as we sold out Winterland and put on the show of our lives. It was a wild mix of rock, comedy, video and dancing as we pulled out all the stops to celebrate the new year, 1976. This is a live mix, no overdubs, so the keyboard and synths are a little funky at the top but it still rocks.
