Here are a batch of photos from days three and four of the Viva Las Vegas festival.
First, the great Dion, who put on a truly fantastic set at the VLV Car Show.
Here's what some doowop fans thought of it.
Also performing at the car show were 60s garage band The Sonics.
Making their debut at VLV were UK family band Kitty, Daisy and Lewis. This is Kitty.
This is the trumpet player with the band, Eddie Tan Tan Thornton.
A surprise hit at the Car Show were the Bop Hounds from Brazil.
Three original rockabilly artists performed on the Saturday night. Here is Huelyn Duvall.
This is Ray Campi, who celebrated his 81st birthday this week.
And here is Joe Clay.
One of the lesser known names making a good impression were Little Lesley and the Bloodshots.
Final act of the weekend was a feast of doowop with three of the all time greats: Eugene Pitt of the Jive Five, Bobby Lewis and Herb Cox of the Cleftones.
Here they are all together.
