The amazon.com description of this is incorrect (it describes the 7" vinyl release). Below is a correct description:Track Listing:1. Good Vibrations 4:452. In Blue Hawaii (instrumental) 2:43"Good Vibrations" is a slightly different edit taken from the album to include the "Our Prayer" reprise that is part of the track before it. "In Blue Hawaii" is a full instrumental edit-- I had been hoping we'd get the "I Love to Say Da-Da" backing vocal isolated ("wah wah ho wah"). Nonetheless, its an interesting piece, there's actually string parts buried below the "water" chant section I'd never noticed, and it is quite interesting to hear the piece without the music.However, while I liked this a bit, I can't imagine anyone who isn't seriously into Brian Wilson/The Beach Boys would care, or deem this worth the price for a two and a half minute instrumental edit, and if you're a serious collector, you probably already own it.
