Back when Classic Rock was just rock, lyrics usually weren't printed on album liners, and to get the chords you had to buy the sheet music.
That was pre-Internet. Today, tracking down lyrics, chords, and tablatures is quick, easy, and free – if you know where to look.
These sites maintain large databases and most all musical genres. If you can't find a song on one of these sites, try the band or artist's site. Sites maintained by fans are also good potential sources.
Happy hunting!
