Question: Who was a famous country singer the original author I Believe to My Soul performed a duet with? Passage 1:Booking Holdings and Expedia Group, both online travel agencies, are the largest travel agencies on the list of top earning travel companies. Travel agencies can be multinational companies, referred to as "multiples" in the United Kingdom. They can also be medium-sized organizations, referred to as "miniples" in the United Kingdom, or can be independent, small companies. They can be structured as a limited liability company, a sole proprietorship, or can be set up as a host, franchising, or consortium structure, such as in the case of CWT. A traditional travel agent may work for a travel agency or work freelance. Helloworld Travel is an example of a franchised travel agency, giving agents access to internal systems for product and bookings. While most point-to-point travel is now booked online, traditional agents specialize in niche markets such as corporate travel, luxury travel, cruises, complicated and important trips, and specialty trips. Other niche markets include travelers with disabilities, travelers over the age of 60, women traveling alone, LGBT tourism, the needs of residents in an upmarket commuter town or suburb, or a particular group interested in a similar activity, such as a sport. Examples include StudentUniverse and STA Travel, which specialize in youth travel, or CWT, which caters to corporate travel. Many use telecommuting to reduce overhead, and/or provide concierge services. Agents can act as "travel consultants" with flawless knowledge of destination regions and specialize in topics like nautical tourism or cultural tourism. Many traditional agents prefer the term "travel advisor" as opposed to "travel agent" to emphasize their advice, expertise, and connections that are of great value. Outbound travel agencies offer multi-destinations; inbound travel agencies are based in the destination and deliver an expertise on that location.
 Passage 2:By 1627 the painting belonged to William Herbert, 3rd Earl of Pembroke (1580-1630), and was at Wilton House in Wiltshire. Either the 3rd or 4th earl presented it to King Charles I of England. After the English Civil War it was sold in one of the sales of the Royal Collection at Somerset House in London on 19 December 1651. Soon after it was in France. The painting was later a highlight of the Pierre Crozat collection which was acquired through Diderot's mediation by Catherine II of Russia in 1772. For a century and a half, the panel hung in the Imperial Hermitage Museum. It was one of the most popular paintings in the entire collection of the Tsars. In March 1931 it was part of the Soviet sale of Hermitage paintings, and bought by Andrew Mellon, as part of his founding donation to the National Gallery of Art in Washington D.C. This and other foundational artworks, including paintings by Jan van Eyck, Sandro Botticelli, and Titian, helped place the National Gallery among the most significant collections of Renaissance art.
 Passage 3:A mixture of songs that inspired his own musical development, together with some of his own compositions, allied to a backing band and orchestra (The Caledonia Soul Orchestra) and several performances (as noted in the album's liner notes) that were recorded in concerts at The Troubadour in Los Angeles, California (24–27 May 1973), the Santa Monica Civic Auditorium (29 June 1973) and The Rainbow (23–24 July 1973) in London. These performance result in what Myles Palmer of the Times reviewed as demolishing "all barriers between the soul, blues, jazz and rock genres". The songs chosen went back to his days with Them with versions of "Gloria" and "Here Comes the Night". His first solo hit "Brown Eyed Girl" was performed but not included on the album until the reissue in 2008. M. Mark called the album "an intelligent selection of songs that draws on six of Morrison's records and five of the musicians he learned from." These musicians were Bobby Bland ("Ain't Nothing You Can Do"), Ray Charles ("I Believe to My Soul"), Sam Cooke ("Bring It On Home to Me"), two songs by Sonny Boy Williamson II ("Help Me" and "Take Your Hands Out of My Pocket") and a cover of a Willie Dixon song, "I Just Want to Make Love to You", which was popularized by Muddy Waters.
