Yeah, this will be to raise money to be donated on behalf of all of the collaborators.
Since you seem unsure about the quality of the tracks from which you’d be willing to donate one, can you link to them here? I’ll have a listen and let you know my own thoughts if you’ll have them. I know that there are a lot of talented but also humble people here so your self-critique may just be humility speaking.
Instrumentals are most definitely welcome. I donated a few instrumentals for the Haiti effort myself.
And, yes, Lenny and Phil are still around. They are on Facebook though.
