Hugorj, I hope to have some time this afternoon for this.
Also, have a look at YouTube for live performance of the song. It turns out what I thought was the bass coming at about 30 seconds is actually keyboards. John Taylor doesn't start playing his bass until around 2 1/2 minutes into the song. I would still tab the keyboard bass part so that I would have something to play during the first half of the song.
So Hugorj, I guess we need to decide what version of the song we are going to tab - Duran Duran's The Man Who Stole A Leopard or the bass cover of the song on YouTube. The bass cover version of Leopard is quite different from what Duran Duran plays, at least in the parts I have looked at so far. I think that if we tabbed the bass cover version, a person who takes that tab and tries to play along to the recorded version is going to be frustrated.
After the G-D-Bb-C phrase you tabbed above (which is actually the first verse, the intro has no bass part), Duran Duran plays G#-G-C-C-G#-Eb-G-G and goes through this twice. I don't know what the bass cover does, but it should reflect these notes at least in part. Cheers.
