The lyric sheet says, 'I've got a tramp's whisker that tells me you still care.' Tramp's whisker is not capitalized, but, Gulf Stream is, which makes me think that she may be refering to a real whisker. When Laura Smith talked about the song on the Peter Gwozski (sp?) show, she also talked about living on an island off Nova Scotia with a lighthouse keeper. Perhaps she is refering to one of his whiskers. The song seemed to be tied into the period that she spent on the island in the Atlantic.
