I'm sorry, I couldn't find the lyrics of "壮美延安（原版正版合唱简谱）" by 陈雷 in my web search results. The closest match I found was a song called "国际歌" (The Internationale) which is a famous socialist anthem[^1^]. Maybe you can try to search for the song you want on other platforms or websites. I hope you can find it soon. ?
