RSO Records 1973 T-Shirt

RSO Records was a record label formed by rock and roll and musical theater impresario Robert Stigwood and record executive Al Coury in 1973. The letters "RSO" stood for the Robert Stigwood Organisation and the company's headquarters were located at 67 Brook Street, in London's Mayfair. In 1978, the label boasted an unprecedented six consecutive number-one singles on the pop charts, holding the top spot for 21 consecutive weeks. RSO would log a further 10 weeks at the number 1 position, giving the label a record of nine in one calendar year. This feat remains unduplicated by any record label to date.
