Iron Butterfly: In-A-Gadda-Da-Vida: Let's face it, the only really memorable song they ever did was this title track, but I wouldn't want to be without it. One side note: The movie "Manhunter" (an earlier movie version of the novel that was made into "Silence of the lambs") uses part of In-a-gadda-da-vida to great effect in the climatic scene. It's worth checking out.
