Well, you cant really say they were "caught" as Noel has admitted similarities in more songs than other people have discovered, such as "Step Out" where Noel admitted in an interview it had a similar chorus to Stevie Wonders "Uptight", when Stevie heard of this he demanded writing credits. Noel wasnt having that so he pulled the song from the album(was due to be on Whats The Story Morning Glory) and put it as a bside, reducing Stevies credit for a song on a multi-million selling album to a mere royalty check for a bside.

I know Led Zeppelin were much more blatently guilty of stealing, except they tried to pass whole other peoples songs off as their own. Jimmy Page would steal old blues songs and put his own name in the credits, and Ive heard the rest of the band were dead against it. off the top of my head it includes "Whole Lotta Love" which is heavily drawn from a Willie Dixon song, Babe Im Gonna Leave You, a folk song by Anne Bredon and White Summer, which is She Moves Through The Fair, drawn from Davey Grahams folk guiitar arrangement. Also the intro for Stairway to heaven is supposedly lifted from a Christian bands song, I think theres a list at ledzeppelin.org, but im not sure. I read the list and theres alot of songs, Communication Breakdown is an Eddie Cochran song, Nervous Breakdown. I agree Oasis are just as big plagiarists, but Noel is proud of his influences and admits them, unlike Mr Page. Great guitarist tho, so I forgive him :)
