The gang's name is Ebonies and Ivories. Just reminding myself and any others having recall issues, which implies both a mixed-race gang AND some musical skills (and mutual care, thankfully!)

🎼🎹"Ebony and ivory live together in perfect harmony
Side by side on my piano keyboard, oh Lord, why don't we?

We all know that people are the same whereever you go
There is good and bad in ev'ryone
We learn to live, when we learn to give
Each other what we need to survive, together alive"🎹🎼 - Ebony and Ivory, Paul McCartney and Stevie Wonder
