This is why I love YouTube, 'How Long' was always a favourite of mine and then I kept hearing it on a tellybox advert, did a search and came across this fantastic version. It features Paul Carrack and Eric Clapton with Eric's regular band members' Henry Spinetti (drums) and Andy Fairweather Low (Rhythm guitar).
I was determined today to post a song by 10cc who, again IMHO, were yet another of the really great bands to emerge from the UK in the 70's. They produced so many hit singles/albums that it was hard to pick just one, but I have and 'I'm Mandy, Fly Me' encompasses, to me, all that was good about 10cc, great wordsmiths and superb musicians.
