Quotes by Ralph Johnson
The fruit we wish to pick tomorrow lies hidden in the seed of today. The goals we are to read and the problems we are to solve tomorrow depend upon today's diligence, hope and faith, today's conviction of the almightiness of good.
They'll be doing general law enforcement duties -- patrol functions, answering calls, ... Pretty much most of the fleet of that sheriff's agency down there was wiped out in the hurricane.
It was a lovely day. We just hope at some stage the government allows the others to visit and do normal family things.
About 17 dry stations that we have stopped at, a lot of places won't even let you in the store.
People used to call us a funk band. But it was a little more complicated than that. We were a fusion group made commercial. We had a lot of progressive chord changes and bebop horn lines and then hooks that a child could sing.
You can not push the river, it's all about God's timetable. Things happen when they're supposed to happen.
Man, LA was crazy. But Rees was a great role model. He didn't smoke, drink or get high. And, at the age of 21 or so, we were very impressionable. So we adopted that lifestyle and work ethic and here we are, still in the game.
