disfluent question: Where no sorry who recorded Walking in Fresno?
context: In the 1970s, the city was the subject of a song, Walking Into Fresno, written by Hall Of Fame guitarist Bill Aken and recorded by Bob Gallion of the world-famous WWVA Jamboree radio and television show in Wheeling, West Virginia. Aken, adopted by Mexican movie actress Lupe Mayorga, grew up in the neighboring town of Madera and his song chronicled the hardships faced by the migrant farm workers he saw as a child. Aken also made his first TV appearance playing guitar on the old country-western show at The Fresno Barn.

proper question: When did the Spanish and Portuguese colonies lose their independance.
disfluent question: When did the Spanish and Portuguese colonies primarily gained no lose their independence?
context: The First British Empire was based on mercantilism, and involved colonies and holdings primarily in North America, the Caribbean, and India. Its growth was reversed by the loss of the American colonies in 1776. Britain made compensating gains in India, Australia, and in constructing an informal economic empire through control of trade and finance in Latin America after the independence of Spanish and Portuguese colonies about 1820. By the 1840s, Britain had adopted a highly successful policy of free trade that gave it dominance in the trade of much of the world. After losing its first Empire to the Americans, Britain then turned its attention towards Asia, Africa, and the Pacific. Following the defeat of Napoleonic France in 1815, Britain enjoyed a century of almost unchallenged dominance and expanded its imperial holdings around the globe. Increasing degrees of internal autonomy were granted to its white settler colonies in the 20th century.
