Yes, Hotel California is a big hit, but so are flamenco pieces like Sevillanas and Farruca, classical warhorses (Albeniz, Villa-Lobos, Tarrega) and lush pop ballads from the Elvis-Orbison era, along with versions of Feliciano's Light My Fire or And I love Her or Malaguena. The thing is, once you learn a few tunes, it becomes really easy to learn many more, and do quickie arrangements in "guitar" keys that use open strings, etc. I don't know how many songs I have in my head, but it seems like many hundreds, I rarely get stumped by requests unless they are contemporary pop tunes, which I am unfamiliar with and rarely tempted by. The looper is an interesting item: even setting up a 4-bar rhythm pattern by playing across the dampened strings like flamencos do can add a nice energy to a solo rendition of a tune.
