Was this 411 owned by a well-known musician?

[Sterly]

Hello all, just wondering if anybody can help here. My friend’s 1975 411 S4 (reg JEU 667N, previously HLB 114N) originally silver, now grey, was reportedly owned by a famous musician but we have no documentation to confirm this, nor do we know his identity. It’s just that a fellow enthusiast who tried to buy the car (my friend beat him to it) told the seller, who was unaware of this prior to selling it. Anyway, we got copies of the records from DVLA and the only possibility seems to be where there’s a gap in the history between 1978 and 1982. Otherwise the history looks complete and unremarkable. Many thanks, Mark
