LAS VEGAS (AP) - Construction is under way on revised plans for a Las Vegas attraction that will bring tourists into Wayne Newton's home.
    
The singer's sprawling Casa de Shenandoah estate has been a flurry of activity in recent months, and work on a tourist attraction to showcase his favorite celebrity keepsakes is almost complete.
    
Revised building plans submitted last month call for expanding a museum space and a theater where he will perform at least occasionally.
    
A Newton-themed car wash will also be larger than originally planned.
    
The revised plans provide for a slightly smaller zoo and car museum.
    
Newton received permission last year to turn his lavish home into a tourist venue.
    
His collection of European antiques and celebrity mementos includes Nat King Cole's watch, Steve McQueen's Rolls-Royce and a Johnny Cash guitar.
