I first heard this song when watching "Белое Солнце Пустыни", and since I'm learning guitar I figured it would be a good song for me to learn. Hopefully when I learn to play guitar better, I will post a recording of me singing and playing this song

не везет мне в смерти
повезет в любви
He's using this "vezet (dat)" to mean "be lucky", right? So does this part mean "I'm not lucky in death, I'll be lucky in love?"

девять граммов в сердце
What? "Nine grams in the heart?" What is he talking about here?

Anyone here know how to play the guitar well? Should I tune my guitar to open G(like the Russian guitar) or just keep it as it is? I can play something that sounds similar, but can't really come close...
Does anyone know where I can find more songs by Bulat Okudzhava online to download?
