I'm actually not doing too badly with it, the notes and the timing are pretty much there, to my ear at least, which is really more testament to the quality of the instruction than anything. It's just the speed of the song that will take some time I think - I'm nowhere near it yet.
I've just (a couple of hours ago) invested in a piece of software called Transcribe which lets me play the actual song itself at a slower speed but keeps it in tone(?) so hopefully I'll work it up to full speed eventually.
I've also started on another song after having seen one of the recommendations in this thread that is demonstrated more than taught by Constantine Isslamow. It's 9 to 5 by Dolly Parton - again selected because it's such a great tune. He has a free and clear transcription of the bass line in a link in the video and a clear shot of him and the bass (both hands) that make it very easy to follow. The resources that are available to us, especially those of us who are beginners, is astounding really.
