the Mobile as the "Rolling truck Stones thing". In Spring 1973, Tapani Tapanainen was hired as the RSM's permanent assistant sound engineer. During the Rolling Stones 1973 European Tour, Mick McKenna joined the RSM and, working with Ian Stewart until his death in 1985, undertook the future development of the mobile studio to suit the changing patterns of work. From 1974 to 1975, the RSM was upgraded significantly. The 16-track recorder was upgraded to a 24-track recorder, and 12 new inputs were added to the existing 20, for a total of 32 inputs. Additionally, a large amount of work was done to improve the acoustic sound of the unit. By the 1980s, the pattern of work had shifted towards more broadcast-oriented products, mostly for major UK clients such as LWT, BBC, Capital Radio, Tyne Tees Television and others. This prompted the inclusion of a synchronizing computer in 1982. This computer enabled audio and video tapes to be run in perfect time, which allowed the Mobile to record a show and then provide finished audio ready for transmission. This feature made it possible to provide the entire sound for several TV series incorporating such artists as Miles Davis, Willie Nelson, Paul Young, and the Chieftains.

The blue livery and yellow sign writing were applied as the colours of the project's sponsor Pernod. Producers Terry Taylor and Mick McKenna worked on about 60 tracks during the course of the project, which culminated with a final show at the Royal Albert Hall in February 1988. The Mobile was subsequently returned to the commercial marketplace, which had become extremely competitive, both financially and technically. It remained in operation until its closure in April 1993. The last recordings made by it were with Mick's brother Chris Jagger, and his band Atcha!, at the unit's base in Pinewood Studios. In 1996 the Mobile, still in its original form, was sold through auction at Bonham’s and taken to the US by Loho Studios in New York City. After a bit of technical service, it was put into action in the underground music scene in New
