Okay...let's be honest. Frank Sinatra and The Beatles are pretty far apart on the musical spectrum. Ole Blue Eyes wasn't a huge fan of The Fab Four. That's not saying they didn't share a bit of musical taste with each other. In fact, Sinatra actually covered the Beatles' "Something" on his 1972 greatest hits package. But there was one song from the 70's that John Lennon and Frank Sinatra agreed was the best of that decade. Which song could unite the legendary Hoboken crooner with the mop top from Liverpool? 

“Reminiscing” by The Little River Band

Besides being one of Frank Sinatra and John Lennon’s favorites, “Reminiscing” was The Little River Band’s most successful single in the U.S., peaking at number three on both the Billboard 200 and Cash Box charts. “Reminiscing” was named Australian Record of the Year at the 1978 King of Pop Awards. In the time since it's release it has become a favorite wedding anniversary song, been used in many movie and tv soundtracks. And in concert, it's definitely a crowd favorite. Give it a listen!
