Chorus of the National Philharmonic Orchestra.

The National Philharmonic Orchestra was a British orchestra formed in 1964 to be used solely for recording purposes. The orchestra was formed by Charles Gerhardt, a producer at RCA Records and Sidney Sax partially to fill the need of Reader's Digest. Before settling on the name in 1970 they went by a variety of other names including the RCA Symphony Orchestra and The London Promenade Orchestra. The orchestra had a variety of musicians and conductors over its lifetime and was used quite often for the soundtracks of films. The orchestra is no longer together.
