In 1969 a band named Three Dog Night did a song written by Harry Nillson named "One" that hit number five on US music charts. The song starts as follows...

"One is the loneliest number that you'll ever do Two can be as bad as one It's the loneliest number since the number one"The following line occurs later in the song...

"One is the loneliest number, whoa-oh, worse than two"The song ends with "one is the loneliest number" over and over again.

Prior to 1969...

Charles Darwin (naturalist, 01809-01882) thought one hour of time was priceless.

"A man who dares to waste one hour of time has not discovered the value of life."Henry David Thoreau (writer, 01817-01862) had thoughts about the number one.

"The man who goes alone can start today: but he who travels with another must wait till that other is ready."Sir Arthur Eddington (astrophysicist, 01882-01944) was quoted saying the following.

"We used to think that if we knew one, we knew two, because one and one are two. We are finding that we must learn a great deal more about 'and.'"And... we also need to learn a great deal more about "or" and "not" and "nor." In many instances one is considered to be true. One and'd with one is one (true), but one and'd with zero is zero (false). One or'd with zero or one is one.

Neil Young (rock n' roller, 01945-?????) says about life... "it's all one song."
