input: Nagas have more language diversity than any other ethnic group or states in India. Naga people speak over 89 different languages and dialects, mostly unintelligible with each other. However, there are many similarities in between different languages spoken by them. Per Grierson's classification system, Naga languages can be grouped into Western, Central and Eastern Naga groups. The Western group includes among others Angami, Chokri, Khezha and Rengma. The Central Naga group includes Ao, and Lotha ; while Eastern group includes Konyak, Phom, Sangtam, Khiamniungan, Yimchunger and Chang tribes. The Sumi group originating in both central and western parts. In addition, there are Naga-Bodo group illustrated by Mikir language, and Kuki group of languages illustrated by Sopvama (also called Mao Naga) and Luppa languages. These mostly belong to the Tibeto-Burman language group of the Sino-Tibetan family of languages. Shafer came up with his own classification system for languages found in and around Nagaland.  The diversity of languages and traditions of the Nagas results most likely from the multiple cultural absorptions that occurred during their successive migrations. According to legend, before settling in the region, these groups moved over vast zones, and in the process, some clans were absorbed into one or more other tribes. Therefore, until recent times, absorptions were a source of many interclan conflicts.  In 1967, the Nagaland Assembly proclaimed English as the official language of Nagaland and it is the medium for education in Nagaland. Other than English, Nagamese, a creole language form of the Assamese language, is a widely spoken language. Every tribe has its own mother tongue but communicates with other tribes in Nagamese or English. However, English is the predominant spoken and written language in Nagaland.

Question: Lynyrd Skynyrd ( LEN-@rd-SKIN-@rd) is an American rock band best known for having popularized the Southern rock genre during the 1970s. Originally formed in 1964 as My Backyard in Jacksonville, Florida, the band was also known by names such as The Noble Five and One Percent, before finally deciding on "Lynyrd Skynyrd" in 1969. The band gained worldwide recognition for its live performances and signature songs "Sweet Home Alabama" and "Free Bird". At the peak of their success, band members Ronnie Van Zant and Steve Gaines, and backup singer Cassie Gaines, died in an airplane crash in 1977, putting an abrupt end to the 1970s era of the band.

In the summer of 1964, teenage friends Ronnie Van Zant, Bob Burns, Allen Collins, Gary Rossington, and Larry Junstrom formed the earliest incarnation of the band in Jacksonville, Florida as My Backyard. The band then changed its name to The Noble Five. The band used different names before using One Percent during 1968.  In 1969, Van Zant sought a new name. The group settled on Leonard Skinnerd, a mocking tribute to physical education teacher Leonard Skinner at Robert E. Lee High School. Skinner was notorious for strictly enforcing the school's policy against boys having long hair. Rossington dropped out of school, tired of being hassled about his hair. The more distinctive spelling "Lynyrd Skynyrd" was being used at least as early as 1970. Despite their high school acrimony, the band developed a friendlier relationship with Skinner in later years, and invited him to introduce them at a concert in the Jacksonville Memorial Coliseum. Skinner also allowed the band to use a photo of his Leonard Skinner Realty sign for the inside of their third album.  By 1970, Lynyrd Skynyrd had become a top band in Jacksonville, headlining at some local concerts, and opening for several national acts. Pat Armstrong, a Jacksonville native and partner in Macon, Georgia-based Hustlers Inc. with Phil Walden's younger brother, Alan Walden, became the band's managers. Armstrong left Hustlers shortly thereafter to start his own agency. Walden stayed with the band until 1974, when management was turned over to Peter Rudge. The band continued to perform throughout the South in the early 1970s, further developing their hard-driving blues rock sound and image, and experimenting with recording their sound in a studio. Skynyrd crafted this distinctively "southern" sound through a creative blend of blues, and a slight British rock influence.  During this time, the band experienced some lineup changes for the first time. Junstrom left and was briefly replaced by Greg T. Walker on bass. At that time, Ricky Medlocke joined as a second drummer and occasional second vocalist to help fortify Burns' sound on the drums. Medlocke grew up with the founding members of Lynyrd Skynyrd and his grandfather Shorty Medlocke was an influence in the writing of "The Ballad of Curtis Loew". Some versions of the band's history state Burns briefly left the band during this time, although other versions state that Burns played with the band continuously through 1974.  The band played some shows with both Burns and Medlocke, using a dual-drummer approach. In 1971, they made some recordings at the famous Muscle Shoals Sound Studio with Walker and Medlocke serving as the rhythm section, but without the participation of Burns. Medlocke and Walker left the band to play with another southern rock band, Blackfoot. When the Lynyrd Skynyrd made a second round of Muscle Shoals recordings in 1972, Burns was once again featured on drums along with new bassist, Leon Wilkeson. Medlocke and Walker did not appear on any album until the 1978 release of First and... Last, which compiled the early Muscle Shoals sessions. Also in 1972, roadie Billy Powell became the keyboardist for the band.
