Bernard Dixon’s band played for the Oxford & Cambridge Highland Ball in 1969. <<ddp:Bolton-Maggs, Tim#523>> (who was on the organising committee for the previous two O&C Highland Balls in Oxford) thinks he may have played with the Trossachs Band in 1965 and with Bob Duncan’s band in 1967 as there wasn’t a wide choice of bands in the south of England at that time and Bernard's commitment to his job with the New Scientist magazine meant he wasn’t always free to play at a particular function.
