Two more corrections (Both Matt's entries)
Here's my "actors should never sing" one-hit wonder contributions:
Eddie Murphy - Party All the Time
Eddie Murphy actually had ANOTHER big single that was on the radio quite a bit in the mid 90's, with none other than the King of Pop himself. The song? Whazzupwitu. It was actually in the top 10 singles for awhile when it was released. The album cover was baby blue with red hearts all over it. Scary.....
Kris Kross: Jump
Many people actually remember Kris Kross for the SECOND single (Warm it up), and some may even remember the third single off that album "I missed the bus" (which borrowed so heavily from Young MC's "Principle's office" that many folks accused them of stealing the lyrics.
Their second album featured a single "Alright" as well as "The Bomb", but neither got them as much play as the 1st album did.
That's my totally Krossed out update.
