They paved paradise
And put up a parking lot
"Big Yellow Taxi" has become an environmental anthem: at least 456 artists have recorded the song, and since 1990 a musician has recorded it virtually every year. Joni Mitchell has recorded it three times, the second, live version in 1974 proving a bigger hit than the original.
