Now here's a rarely seen item... especially in this condition! Ivan is Jerry Allison, the Crickets drummer. This terrific track features Buddy Holly on lead guitar. The flip side is another uptempo rockabilly number (different--and better--than the one that appears on the 1967 reissue), likely also featuring Holly.... as well as some more interesting vocal experimentation. By the way, Ivan made no albums, just a couple of singles. Note: This beautiful promo copy comes in a vintage Coral Records factory sleeve. The labels grade Near Mint with a faint touch of storage wear. The vinyl looks almost untouched but grades Near Mint because it's not completely flat (I noticed this when playing the B side)... though that has no effect on the audio, which is distortion- and noise-free with no notable flaws  pristine Mint!
