About these numbers

Concert figures describe 2,181 distinct archive record IDs from 1962-07-12 to 2024-07-21. Separate same-day record IDs remain separate; they have not all been reviewed as unique performed concerts.

1,506 records have stored song entries; 675 do not. Complete-setlist coverage is not established. Missing entries do not establish that a song was not played.

Song observations count distinct record IDs with a matching title after playback entries are excluded. These are documented appearances, not verified full-song performances. Tour groupings can include warm-up dates.
