Back from the IPL, Australian speedster Brett Lee is now busy with his music career and is set to release his band White Shoe Theory's maiden single.

The affable pacer, who competed for the Kolkata Knight Riders in the IPL, does back-up vocals and plays bass in the band which he founded with friend Mick Vawdon. "We're going to launch our single shortly, so it's all happening," Lee was quoted as saying by 'The Daily Telegraph'.
