Founded in 1979, the Harvard Din & Tonics all-male jazz a cappella group have performed across the world for years, spreading joy as a public service project by the Ivy League university.
When they're not performing together with jazz icons, playing in front of US presidents and ambassadors, or making appearances on TV and film, the group help out with the community and with charitable organisations. Their most recent outing saw them collaborating with the Autism Resource Centre to drum up publicity for A Very Special Walk — their annual fundraising event — this Saturday.
How? By going viral, of course. And so the Harvard Din & Tonics dressed in their standard getup (white tie, tailcoats, lime green socks) and led people in public renditions of "Stand By Me" across town.
