One half of Beagle II here - Beagle is a composite entity consisting of me and my sister "Nosebag". This puzzle is a tribute to a great influence on both of us. Share and enjoy!

Thanks Beaglell & welcome (or welcome back!) My faves: 11a, 20a, 2d, 3d & 17d. A few issues in some of the others, but a handful of points that probably need fixing are spelling mistake in 19a, 14d's fodder having an extra A instead of an E, and a lack of clue for 21d. Thanks again!

Thanks Beagle ll, once I heard the news, I was hoping someone would take this on. A worthy tribute to a true genius...very pleased to see 19a s making an appearance!

Excellent tribute! As for 5d, which on another forum you said you regretted you had to change, perhaps consider this OED entry: https://www.oed.com/search/dictionary/?q=mofo

Really lovely! A fitting tribute to the master.
