Since bending is so important for playing blues harp, I thought it might be a good idea to link to an amazing video by Florence Gacoin-Marks where all first octave bends are used in a short, slow jazzy melody: Glenn Miller’s “Moonlight Serenade”. The diatonic harp tabs are given in the comments below the video.
Now I have been inspired to practice these bends even more diligently! 
I hope that you will be as well.
