as already said....back when i was actively gigging, it just depended on the type of crowd me and my buddy Red were playing for...examples:
in the mood
panhandle rag
speedin' west
bud's bounce
honky tonk
green onions
tequila
cissi strut
cannonball rag
we did lots of Chet Atkins type instrumentals, lots of big band stuff we were able to pull off quite succesfully since we both used MIDI tone generators.
other instrumentals later in a gig interspersed with Red's vocals would be:
sleepwalk
harbor lights
i'm a fool to care
vaya con dios
sugarfoot rag
malaguena....our version....don't ask
theme from Dr. Zhivago (somewhere my love)
of course the "gotta do" stuff
wildwood flower, but with banjo, piano, sax, fiddle, via MIDI
under the double eagle
foggy mountain breakdown..
steel guitar rag
drifter's polka
lotsa others
