Hey that pic is of an Irish group named Thin Lizzy.
They had hits with songs such as "The Boys Are Back In Town" (recently used on the Toy Story 2 soundtrack) and "Sarah". My uncle Joe (now 58ish) used to drink with their frontman/lead-singer Phil Lynott. Phil died tragically young as a result of an accidental drug overdose... accidental as opposed to the very deliberate overdoses my uncle Joe regularly indulged in and routinely survived without incident.
Interestingly, Phil Lynott's mother is a very well-to-do, educated, prim, proper and respected lady. Despite being a single mother (a stoneable offence in 60's Ireland), having a child (Phil) out of wedlock (another stoneable offence in 60's Ireland), and a half-caste child at that... she simply refused to acknowledge there was anything unusual about Phil. Seems she was simply too respectable, and 60's/70's Catholic Ireland was too polite for anyone to ever say anything.
To put things into context: Phil would often tell the story about how growing up in Ireland he never, NEVER saw another black person till a chance encounter with a Nigerian medical student when he was sixteen. That's how rare and ununusual it was for anyone to see a black person in Ireland right up until the mid-80's.
However, Phil's sense of humour was such that he was immediately recognisable as a true and true Irishman. In interviews with magazines and television channels, when asked about his mixed heritage he would simply blank the interviewer... seemingly incongrous, he would start asking the other band members why they had never told him he was black. "Is it noticeable?" was one of his favourite refrains.
If the other band members managed to keep a straight face he would then pretend to phone his family and have a screaming argument over the phone in the other room. "Does Dad know?"
Wicked sense of humour.
