You brought on a great journey this week man, sounds a lot like my own youth, hearing the tunes that my four older sisters (well three of them anyway!) and two brothers. It was definitely what influenced my taste in music. Wish you were here is genius, as is the album, only 5 tracks but man are they good, Shine on you crazy diamond in memory of Syd is very very special, imagine a 13 minute track getting released today! Just wouldn't happen, you do well to get to 3 minutes... Love a long song that builds... No Abba influence in my house growing up, so not a big fan of their really popular tracks, but Chiquitita was one of their better ones, and sure anything by Simon or Garfunkel will get the lend of my ear and sure Stairway to Heaven talks for itself and I know what you mean about Guitar shops, they bring it in on Wayne's World if I remember correctly..
