Paul McCartney's recent "Carpool Karaoke" appearance on CBS' The Late, Late, Show with James Corden has pushed the Beatles and McCartney back onto the charts. According to Billboard: "McCartney ranks highest on Hot Rock Songs via the Beatles' 1970 Billboard Hot 100 Number One 'Let It Be,' which debuted at Number 18; older songs are able to re-enter the Hot 100 or its corresponding genre-based hybrid charts, like Hot Rock Songs, if they have meaningful reasons for their return and rank in a chart's top half. After McCartney performed 'Let It Be' on 'Carpool Karaoke' with Corden, it debuted thanks to 1.5 million U.S. streams (a 68 percent gain) and 10,000 downloads sold (up 973 percent) in the week ending June 28th according to Nielsen Music."

In addition to that, "Macca's" new "Double A-sided" single is picking up traction, with "Come On To Me" -- which was performed in the Corden sketch -- entering at Number 24 with "799,000 U.S. streams, 631,000 radio audience impressions and 10,000 sold" as well as hitting Number 34 on Billboard's Adult Alternative Songs airplay chart. "I Don't Know," debuted at Number 39 on the Hot Rock Songs list with "428,000 streams, 207,000 in airplay audience and 4,000 sold."

The Beatles are benefiting from the appearance as well on the magazine's Rock Digital Song Sales chart with, "Let It Be" hitting Number Six, "Blackbird" Number 10, "Hey Jude" Number 11, "Penny Lane" Number 15, "Ob-La-Di, Ob-La-Da" Number 18, and "Here Comes the Sun" peaking at Number 24.

Paul McCartney maintains that the reason why the Beatles still hit such a multi-generational chord with fans is because the music reflects back the best of humanity: "Number One, it is a force for good. We have a lot of power -- particularly in the Beatles days. Even now, y'know? But then, you had a lot of power. And we always used to say to people, 'Look, we never used it like Hitler. We never sort of said, 'Follow us and go crazy and do something.' But generally we were talking about peace and love and fairly optimistic and positive things, y'know, in the '60s."

Paul McCartney will headline the Austin City Limits Music Festival. Tickets are now on sale for the Texas festival, which takes place across the weekends of October 5th through 7th and the 12th through the 14th. The actual date of his spot has yet to be announced.
