If you think internet bass tabs are horrendous, you should see tabs and chord sheets for guitar. Oy veh!

There's more to muck up there.
I've been crowing, harping, chirping, about my bass line for My Sweet Lord in the key that I believe the studio recording was done in. At least when I play it on guitar along with the recording they are in tune. I found only one decent chord sheet, and even then I had to work out the bass line from the chords.
Face it friends, there's just precious little out there on the internet unless you download published sheet music, and even then it could be in a key different from the studio recording.
