AC/DC’s secret weapon for the last 36 years has been Angus’ brother, Malcolm Young. While Angus spins around on the ground wearing shorts, Malcolm holds it down like nobody’s business on rhythm guitar, usually playing his Gretsch signature model. Malcolm is said to be the brains behind all of AC/DC’s business dealings, and anyone’s measure of success, he has done all right. He turns 56 today.
