RE: does somebody knows what it means in a gada da vida?
The title was supposed to be "In The Garden Of Eden." Someone had written "In-A-Gadda-Da-Vida," possibly while drunk, on a demo copy. A record company executive saw it and decided to use it as the title, since it sounded mystical, and Eastern spirituality was big at the time, with The Beatles going to India and The Rolling Stones experimenting with Indian instruments.
Title loosely translates as "In The Garden Of Life."
