Under The Covers: Other Artists Covering Beatles Songs: ‘I Feel Fine’- Charles River Valley Boys. Here is a different take on a Beatles classic. The Charles River Valley Boys were a bluegrass and who in 1966 did an album of Beatles covers called Beatle County- I have the album-and enjoyable listen. Here they take on “I Feel Fine” which The Beatles released as a single in late 1964- and racked up another #1 hit. A ground breaking single best remembered as one of the first times feedback was used. No feedback here.
