There has been rampant speculation about the planned upcoming remix of "Immigrant Song" by recently reunited Led Zeppelin, and how Pendulum would handle it. Since there's been no talk of other songs being remixed, the possibility remains open that Led Zeppelin, long resistant to releasing single, may be releasing there first one after all these years. The band built its reputation on the completeless of its LPs in the late '60s and early '70s, so it would be fitting for the iTunes generation to turn even the most album-oriented band more single-focused.
