"Tell Me Why" is the opening track on Neil Young's album After the Gold Rush. Written by Young, it was first introduced during the Crosby, Stills, Nash and Young shows of 1970 prior to the release of Déjà Vu.
Musically, the song marks a shift from the hard rock of 1969's Everybody Knows This Is Nowhere and bears more folk and country influences, which would continue onto 1972's Harvest. The only instruments are two acoustic guitars, played by Young and Nils Lofgren. .
