Here's a bald celebrity I didn't see listed here (after a search): Thomas Dolby.
http://youtube.com/results?search_query=thomas+dolby&search=SearchI always liked his music, but even if you never bought his records, chances are he's made money off of you. He wrote the Beatnik software that plays MP3 ringtones on almost every cellphone.
Speaking of musicians I like, 30 years after Rush recorded the song, "I Think I'm Going Bald", Neil Peart of Rush has finally started to lose his hair, though it's mostly a receding front hairline.
Alex Lifeson and Geddy Lee, on the other hand, have yet to lose any despite their age (55). Maybe it's their east European family lines (Serbian and Polish jew).
And yes, I will get around to writing that intro post about myself....
