"The Zephyr Song" was the second single released for the Red Hot Chili Peppers' eighth studio album By the Way. The song, as a single, was released in two parts. Both editions held two previously unheard-of B-sides, making it, collectively, hold four non-LP tracks. This is the largest amount of accumulated unreleased studio recorded B-sides any solitary single the Red Hot Chili Peppers have ever released.
During the By the Way tour, the song was played extensively at virtually all live concerts. Since the release of the Red Hot Chili Peppers' newest album, Stadium Arcadium (and its subsequent tour), however, "The Zephyr Song" has since been completely removed and detached from any set lists. It has not been played once since 2005.
