Not only Andrea, as I mentioned in an other thread:
I found some other actors...
From the sitcom "Alf"
As mentioned by Shoe Dick in the episode's "Rock and Roll Girl" Thread, Josh Blake, who played "Jake Ochmonek" is the guitarist of the "Gutter Cats"
And, Andrea Elson, who played "Lynn Tanner" on Alf, is one of the brides maides in the "Wedding Show".
As i mentioned in the "How did i love thee" tread, David Leisure played the booking man "Nick "The Fish" Mints" in Alf, and also a TV executive which office gets completely stripped down as Alf fakes TV rates for his favorite show "Polka Jamboree"
And, there is more: Beverly Archer, who played "Mrs. Byrd" in Alf's "Somebody watch over me Part 1-2" is also Bud's Boss in the "Virgin Hotline" and trying to sue Bud when he masturbates in High School
