The Sheriff’s Support Group of Altadena summer concert series moves from strength to strength, as “Upstream” put the Farnsworth Park crowd on their feet with their mix of reggae and soca music — and a moment of immigrant patriotism as they waved the flag, shouting “Freedom of speech!  Freedom of religion!”

Besides some originals and reggae classics, they put their own touch to some classic rock numbers, from the Beatles to Van Morrison and more.

And of course, we have video — it’s a little shaky, but gives a good sense of the high energy and fun.
