Just watching footage of a 1975 concert... think it's the Christmas Eve one, and I suddenly remembered a performance at another show but I can't quite place it. The song is Death on Two Legs, and at about 1:26 in, Brian makes the Red Special do a fart-like noise, and Freddie gets a weird look on his face at that point whilst playing the piano hooks. Can anyone tell me which concert that might be? Something in my mind tells me it's Houston '77 or something like that... but I'm probably wrong.
