I don't know exactly what part you are talking about...........but I here's the part I'm thinking of. I play the chords a little different. I'll give you two ways.
Ab / Ab B D F Ab (Ab, Ab, Ab, Ab play this with your pinky)
(A, B)
Ab / Ab B D F Ab
the other way is.................
D / D Gb Bb C
(E, Gb)
D / D Gb Bb C
The second one I got from a chord chart. It doesn't sound right to me. But I could be playing it wrong. Hope this helps.
