Ten Grands - Cancelled

Ten Grands Promotional Video

Thank you for committing to be part of our annual event, Ten Grands.

We’re so sad the event we were all looking forward to must be cancelled due to the current COVID-19 pandemic. This event is always such a fun opportunity to see and share our music with you and thank you in person! But… the show will go on in a re-invented capacity. As you may be aware, it’s one of our largest fundraisers of the year and we were counting on raising $100,000  in order to fund the good work of Play It Forward’s growing piano lesson program in North & Northeast Portland schools.


  1. Convert your ticket into a much needed tax-deductible donation 
  2. Receive a full or partial refund by emailing
  3. Or…Make an additional donation to Play it Forward

Please note that you will automatically receive a refund if we have not heard from you by September 30th.

We truly appreciate your generosity and are so grateful for your help to meet the needs of the kids we serve. Your continued support now will make a huge difference to those who rely on us including our performing artists, stage designers and Play It Forward recipients. It means so much to us that you continue to support our mission at this critical time. 

Again, thank you for your generous heart and kind understanding. We’ll stay in touch and keep you regularly updated. 

Stay safe, until we can meet again,

Marietta and Michael Allen Harrison
