My family is throwing a big party for my grandmother's 90th birthday next month, and these showboaters are all doing their own acts, singing, dancing, or whatever they do. Since I don't do much these days other than play the bass, I need to find a piece that I can play as a stand alone bass song, and something that a lady of her vintage will appreciate. I plan on using a standard tuned 4 string and bringing my Fender Rumble 100. I have a month to practice it, so it can be moderately difficult. I'm drawing a blank, so suggestions would be appreciated.
