The Young Ones, recorded by Cliff Richard & The Shadows, is the title song to the 1961 film and its soundtrack with the same name. It was released as a single the following year and went straight to No. 1 in the UK Singles Chart, the first British single to do so.
The arrangement is done in the key of G with relatively easy chords, and a straightforward progression, which should make it doable for every guitar player.
Beginners could, of course, keep the strumming really simple, but the challenge for the ones who are already comfortable doing so would be to include a 'bounce'. This is a typically Shadows sound in my opinion, sometimes done by the drums, or the guitar, or both etc.
It makes the song, along with the several 'breaks' throughout the arrangement, much fun to play. It certainly adds to ones rhythm guitar playing skills.
