To Micca:
Further to Rick's message there is a more simplified arrangement of Dallas Rag (and it's not easy either but definitely easier than Grossman's verion) and it's done by David Bromberg. He also combines it into a medly with a watered down version of Maple Leaf Rag.
There is also tab available for it, if you have either the Tabledit Program or the Guitar Pro tab program. If you have either of these, let me know and I'll email you the tab arrangement.
