Jeff Lynne (recently inducted into the Rock and Roll Hall of Fame) was a very close friend of George Harrison's and Monty Python, one of the Traveling Wilbury's, was credited for the "ELO" Sound... If you listen to their discography, you can definitely hear the influence the Beatles had on Jeff. If I had to suggest one album to you, it would be "A New World Record" , or maybe "ELO's Greatest Hits" (which has "Evil Woman" in it) or "Out of the Blue"
Other than Jeff Lynn's distinctive vocals, the ELO sound is recognised by a classical twist to Jeff's Beatles Inspired compositions.... They even had a song called "Rockaria" a play on Rock + aria (a long, accompanied song for a solo voice, typically one in an opera or oratorio) in which the story revolves around someone trying to take out a classically trained opera singer (Beethoven, Puccinni and Wagner are in the lyrics)
The use of strings, intrinsic to the song's vibe....
Also another huge hit for ELO, even here in the States, was Telephone Line, also heavy use of strings....
There was a time "Mr Blue Sky" was used in every other movie, every other commercial....possibly ELO's most lucrative song because of it's commercial use...
Behind the Beatles, ABBA and the Eagles, one of my all time favorite bands
