Aqualung may refer to:

Computer software, or just software, is a collection of computer programs and related data that provides the instructions for telling a computer what to do and how to do it. Software refers to one or more computer programs and data held in the storage of the computer for some purposes. In other words, software is a set of programs, procedures, algorithms and its documentation concerned with the operation of a data processing system. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software. The term was coined to contrast to the old term hardware (meaning physical devices). In contrast to hardware, software "cannot be touched". Software is also sometimes used in a more narrow sense, meaning application software only. Sometimes the term includes data that has not traditionally been associated with computers, such as film, tapes, and records.

James Douglas "Jim" Morrison (December 8, 1943 – July 3, 1971) was the lead singer and lyricist of the rock band The Doors, as well as a poet. Following The Doors' explosive rise to fame in 1967, Morrison developed a severe alcohol and drug dependency that culminated in his death at the age of 27 in Paris. He is presumed to have died from a heroin overdose, but as no autopsy was performed, the events surrounding his death and the exact cause of it continue to be disputed by many to this day.

Morrison was well known for often improvising spoken word poetry passages while the band played live. Due to his wild personality and performances, he is regarded by critics and fans as one of the most iconic, charismatic and pioneering frontmen in rock music history. Morrison was ranked number 47 on Rolling Stone's list of the "100 Greatest Singers of All Time", and number 22 on Classic Rock Magazine's "50 Greatest Singers In Rock".

James Douglas Morrison was born in Melbourne, Florida, to future Rear Admiral George Stephen Morrison and Clara Morrison. Morrison had a sister, Anne Robin, who was born in 1947 in Albuquerque, New Mexico; and a brother, Andrew Lee Morrison, who was born in 1948 in Los Altos, California. He was of Irish and Scottish descent.

Lester William Polsfuss (June 9, 1915 – August 13, 2009)—known as Les Paul—was an American jazz and country guitarist, songwriter and inventor. He was the inventor of the solid-body electric guitar which made the sound of rock and roll possible. He is credited with many recording innovations. Although he was not the first to use the technique, his early experiments with overdubbing (also known as sound on sound),delay effects such as tape delay, phasing effects and multitrack recording were among the first to attract widespread attention.

His innovative talents extended into his playing style, including licks, trills, chording sequences, fretting techniques and timing, which set him apart from his contemporaries and inspired many guitarists of the present day. He recorded with his wife Mary Ford in the 1950s, and they sold millions of records.

Among his many honors, Paul is one of a handful of artists with a permanent, stand-alone exhibit in the Rock and Roll Hall of Fame. He is prominently named by the music museum on its website as an "architect" and a "key inductee" along with Sam Phillips and Alan Freed.
