Not only is the looking for their songs in notebooks annoying, but also, some musicians, when introducing an original song, go into long-winded, unnecessary, BORING, explanations of every detail of how, why, and every emotional aspect of writing their piece. Of course, those songs may have personal significance to the singer/songwriter, but the audience, by and large, don't care about all that. Just play the piece, and let the music speak for itself. Save the 'interviews' for interested listeners. Word may/should spread, by itself, IF people like the song!
And a word to the wise: DO NOT place TWO slow blues pieces back to back. You will lose your audiences attention....whether you think so or not!...(Top Professional musicians know this, as well).

Good luck with good licks, and keep playin'!!
