There's a beginner tab in the tab archives for Away in a Manager. It's in the key of G. Would that work? Does it HAVE to be in the key of D? If so, perhaps someone could transpose it from G to D for you. Go here: hangoutstorage.com/banjohangou...32012.pdf
I don't find any tab for Go Tell it on the Mountain.
And, I'm moving your thread from the bluegrass forum to the tab forum where it belongs.
We have a massive list of tabs for banjo in the tab archives and all our tabs are FREE. You will, however, need the proper software to download, play and print some of the tabs. Most of the software will be aware here: banjohangout.org/w/links/brows...byid/v/37 , just scroll to the appropriate software and download. Most downloads are also free (at least for the demo models).
Feel free to peruse our tab archives and download/print those you need. Tab archives are located on the left hand side of the page. Under Learn click on banjo tab library and then either type in the name of the tab in the search window or search alphabetically.
