Similar sounding bands.

Black Crows and the Stones. Duh.

Geoff - Good call. Black Crowes & Stones similarity - that I can absolutely hear.
BUT I'll see your Stones and raise you a Humble Pie with Chris R. absolutely
channeling Steve Marriott. Leastways in the first couple of LPs.

Hey Marty - I respect your judgement! Do me a favor (I'm really not issuing a
challenge) tell me what Oasis tracks might best show that Beatles connection. As
I said, I was way late to the Oasis party so must have missed them. I'm very
curious about it.

Yoko Ono and chalkboard.

Ghost,

Probably the quickest way to hear similarities is to check out the video mash-ups from the time of Oasis' moment in the sun, when wags were bashing them for their pilfering of Beatles material. I'd guess that some of them are probably still available on YouTube. I know that there was one called "A Day in The Wonderwall" which overlayed the vocals from "A Day In The Life" atop the instrumentals from Wonderwall.

There was also a popular one that IIRC mixed Let It Be with Don't Look Back in Anger and another one that mixed an Oasis song (can't recall the title) with the vocals from "I Should Have Known Better". There are a bunch of these videos out there, they're occasionally amusing, and they tend to illustrate the point at hand. See for yourself if you find them convincing.

Happy Listening.

Ozzy,

Personally, I'd go with Yoko Ono and NYC subway train making tight turn at high speed.
