The Pasadena Roof Orchestra (PRO) is a contemporary band from England that specialises in the jazz and swing genres of music of the 1920s and 1930s, although their full repertoire is considerably wider.
Arthy purchased a cache of original musical arrangements dating from the 1920s stored in the attic of a lady in Manchester, and the strength of this find reinvigorated the flagging fortunes of the earlier band.
The orchestra toured the United States in 1993 and 2001 (their 25th Anniversary album cover featured a photo of the band in front of the Santa Fe train station in Pasadena, California).
Whilst literally hundreds of the UK's finest jazz musicians have on occasion performed with the Orchestra, this is a timeline of the regular members.
In 2003 the Pasadena Roof Orchestra released a DVD of the 30th Anniversary live concert at Regent's Park, London, with guests.
