Seems like a pretty good deal for the iconic John Williams score on vinyl.
Composed by John Williams, the score for Raiders of the Lost Ark was the only score in the series performed by the London Symphony Orchestra, the same orchestra that performed the scores for the Star Wars saga. The score is most notable for it's inclusion of the iconic and now ubiquitous 'Raiders March,' which came to symbolize Indiana Jones and was later used in the scores for all subsequent films. Raiders of the Lost Ark received an Oscar nomination for Best Original Score in 1981.
Stupidly, I left my original copy out on the footpath with 80 other albums about 20 years ago. (People were fighting over them!)
