I've found, for the most part, that trying to introduce Fleetwood Mac (or more specifically Lindsey Buckingham) to my friends using just a song from a cd just doesn't cut it. The best way is for them to
see the talent.
I converted my best friend (whose favorite bands are Tool, A Perfect Circle, and Nine Inch Nails) into a Buckingham fan by taking her to two of the shows on the Say You Will tour - a rather expensive but effective means of doing it. After the first concert her response was "I have three words: He is amazing!"
However, I tried that tactic with another friend but to no avail, despite being only maybe two feet away from the stage. I think the situation wasn't helped by the fact that he spent the night being hit on by some bikini-top clad teeny-bopper who kept yelling "Stevie, I want to have your baby!" and a middle aged man with a receding hairline. My friend also kept insisting that he questioned Lindsey's sexuality. Personally, I think his gaydar is malfunctioning -- either that or it was wishful thinking that he'd never admit to.
My former manager was converted to a Buckingham fan because I had her watch the Dance. After that, whenever a Lindsey song came on the radio or if I played a cd she'd ask "Is this song about Stevie?" and if I said no her response was "Good. I really like this song and would hate to think that it's about her."
If I were to try to convert someone now, I'd have them watch "Come" from Live in Boston.
