He's definitely playing it on a D diatonic harp. Email me directly at jpmcbride@yahoo.com and I'll email you an .mp3 file of the harp solo slowed down to 50%. I was working on this solo at one time.
just joined... i got some learnin' to do. I am looking for what goes on with the harp solo in the Huey Lewis tune working for a living. Any direction? i gather the D harp for an A keyed song is right unless he is playing 3rd on a G chrom. Can anybody point me in the right direction?
