"We had to change our names because we were getting a few problems from the people in America and that was the only way round it.
"Later on we went to LA and did some charity work and after that Dan Aykroyd sent me his autograph saying: 'Dear Bill, I am ready to believe in you'. So that was lovely."
The duo even managed to get their passport and driving licence photos approved wearing the trademark hat and shades.
Jake says: "I found myself saying to someone at the passport office: 'Look, I wear my sunglasses all day and all night and I sleep with them on,' and within a week the passports came back with hats and shades."
