Mike Watt doesn't look like a punk. With his fondness for plaid shirts and bushy mustaches, he looks, actually, more like a regular working-class guy — a steel worker, or a sailor like his father.

He shares the same work ethic too. Watt, who plays in 15 different groups, has just finished his 66th tour. At 50, he is one of the grand old men of punk rock.

"The punk I come from wasn't really a style of music, it was just weird people," says Watt by telephone from his home in San Pedro, California ahead of his forthcoming 14-date tour of Japan.
