A "Bloomberg Businessweek" article shortly after that decision noted that a Ninth Circuit judge's interpretation of the laws implied that key elements of many classic rock songs, including "Stairway to Heaven", that were recorded prior to 1978 were not protected by copyright to begin with. The panel declared that the scope of copyright for those songs is limited to what was included in the deposit copy of the song's sheet music provided to the Copyright Office; at trial Page had testified that the deposit copy included neither the intro that was under dispute nor his guitar solo. "Bloomberg" reporter Vernon Silver found that the deposit copies of other classic rock songs from that era, such as "Hotel California", "Born to Run" and "Free Bird", include only the song's basic chords, lyrics and melody, without any solos or other distinctive musical touches. Copyright law experts could not say whether those elements are copyrighted or not; Led Zeppelin's lawyers have argued they are even if not included in the deposit copy. Silver made an electronic mashup of several of these elements from different songs and included it with the article.
