I know that the issue of on-bike entertainment is almost as contentious as the subject of H*lm*ts , you are either for it , or against . I use entertainment only on my pushbike , and only on out of town back roads and lonely cycle tracks . As an old man , my tastes in music are rooted in the 1950s , 60 s and 70s . There is a nationwide network of Gold Radio on the AM band that suits my tastes . No Ipods , stereo , or modern gadgets like that , I use a small transistor radio on a home made handlebar bracket . As such radios are a bit directional , the bracket incorporates a small turntable , so I can turn the radio if the signal fades . I do not use any form of headphones , and a keep the volume at a low level that is scarcely audible to passers by . But today , I did not use the radio , as I have an earworm . I watched "Family Guy " the other night , and there was a scene where Peter Griffin ,Lois , and Quagmire were at a dance . The band were playing a slow dance tune [ we used to call it a smooch] Called Earth Angel . Originally recorded by the Platters in 1954 , It follows the classic chord progression of C major , A minor , F major and C seventh . Actually I do not remember hearing it before , but I could not get it out of my head . I was foolish enough to find it on Youtube ,and play it several times . So now it has become an earworm . Like a continuous tape loop that plays in my head 24 / 7 . I feel like walking into the chemist`s and asking for some earworm tablets ....
