I felt almost certain this was mentioned somewhere on this forum when it happened last year, but now I can't find it anywhere. In any case:
Ms. Callaway did this Sondheim tribute for four nights last March (https://54below.com/events/to-steve-with-love-liz-callaway-celebrates-sondheim/) (2022) at 54 Below, livestreaming one (https://54below.com/events/live-from-feinsteins-54-below-to-steve-with-love-liz-callaway-celebrates-sondheim/) performance, before returning for an encore run (https://54below.com/events/to-steve-with-love-liz-callaway-celebrates-sondheim-feat-nick-callaway-foster/) and livestream (https://54below.com/events/livestream-to-steve-with-love-liz-callaway-celebrates-sondheim-feat-nick-callaway-foster/) in June, and then releasing a full audio recording in November (occasioning a release party -- where else? (https://54below.com/events/to-steve-with-love-liz-callaway-celebrates-sondheim-album-release-show/) -- which I'm guessing was essentially another full live encore of the entire show/album).
And with all those chances to see and/or hear it, I'm just now finally getting around to listening to the entire thing (27 tracks in all). It's lovely.
(from a non-Sondheim-specific 2021 performance (https://54below.com/events/liz-callaway-3/) at 54, this song and story later found their way into To Steve With Love – go figure).Available on CD (https://www.amazon.com/Steve-Love-Callaway-Celebrates-Sondheim/dp/B0BKLQJFWK/), Spotify (https://open.spotify.com/album/6gQ5MYI8iqSKoasNPw43X8), YouTube Music (https://music.youtube.com/playlist?list=OLAK5uy_mhwBdzirzpjVak30EiwP-QWDvTSRvJtLg), Pandora (https://www.pandora.com/artist/liz-callaway/to-steve-with-love-liz-callaway-celebrates-sondheim/ALvPcx9q7XrbxmX), Apple Music (https://music.apple.com/us/album/to-steve-with-love-liz-callaway-celebrates-sondheim/1652573126), and wherever else you get music.
