Randy Travis

Randy Travis (born 1959) is an American country and gospel music singer and songwriter. He has recorded more than 20 studio albums and charted more than 50 singles on Billboard's Hot Country Songs charts, including 16 that reached the number-one position. Travis's commercial success began in the mid-1980s with the release of his album Storms of Life, which was certified triple-platinum by the Recording Industry Association of America. His major songs include "On the Other Hand", "Forever and Ever, Amen", "I Told You So", "Hard Rock Bottom of Your Heart", and "Three Wooden Crosses". Travis is noted as a key figure in the neotraditional country movement, a return to more traditional sounds within the genre following the country pop crossovers of the early 1980s. Since surviving a near-fatal stroke in 2013, which severely limited his singing and speaking ability, he has released archival recordings and made limited public appearances. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
